Key Takeaways:

  • Process Before Platform
    Map your customer journey first. Then choose the tools that support it. Automation without clarity just amplifies the chaos.
  • Build a Single Source of Truth
    Stop juggling multiple systems. Pick one core platform for data and integrate everything else into it.
  • Automate the Repetitive, Personalise the Rest
    Automate the predictable. Keep the personal moments human. Thatโ€™s how you stay connected while scaling.
  • AI Should Be Your Teammate, Not Your CEO
    Use AI to assist, not decide. It should lighten your cognitive load โ€” not replace your judgment.

If your business feels like itโ€™s held together with spreadsheets and wishful thinking, this episode will show you how to scale without losing the soul of your brand.

How Stress Affects Sales, Pricing and Business Growth

Mar 24, 2026

This blog breaks down why stress changes the way you sell, lead, and decide, and what to do about it.  

 

Key takeaways

  • Regulating your state before a high-stakes conversation can change the quality of the decision you make in that moment.

  • Chronic pressure pushes smart founders out of strategic thinking and into survival-based reactions.

  • A narrow window of tolerance makes pricing, boundaries, and leadership harder right when your business needs them most.

  • Small, repeated decisions drain the same mental energy you need for clear commercial judgment.

  • The state you bring into a client interaction changes trust, authority, and openness before you say a word.

“Stop treating your psychology as something to manage around and start treating your nervous system as infrastructure.”

 


 

If you have ever lowered your price too quickly, loosened a boundary you meant to hold, or watched your best strategic work get pushed aside by inboxes, pings, and client demands, this is for you.

I see this pattern all the time with coaches, consultants, and specialist service providers who are brilliant at what they do. They categorically do not have a strategy deficit. They have a state problem. Their business has reached a level of complexity that their nervous system has not yet been trained to hold.

That matters more than most business advice will admit. Because when pressure becomes chronic, stress does not just affect your mood. It affects your sales conversations, pricing decisions, your ability to think long-term, and the quality of leadership your business receives from you.

“There is nothing wrong with your strategy if you're stuck.”

 

Why stress sabotages sales conversations and pricing decisions

Most people think poor pricing decisions come from low self-confidence or dodgy sales skills. Sometimes that is true. More often, it is stress. 

Picture the moment. You are on a call with a strong prospect. They seem like they're a great fit. They have the budget. You want the work. Then they hesitate. Maybe because of the price. Maybe when you ask for a decision. Or... maybe they ask you to justify the investment.

Before you have consciously decided anything, you start adjusting. You explain more. You fill the silence. You row back on something you've said to "compromise". You try to make the offer easier to buy.

That is not just a mindset wobble. It is your survival system reading hesitation as a threat and trying to reduce risk fast.

“That is quite literally your biology making a commercial decision on your behalf.”

This is one reason stress affects sales conversations so much. The bigger the monkey on your back when you go into situations like those, the more likely you are to confuse tension with danger and make a reactive move that costs you margin, authority, or both.

 

What happens in the brain when business pressure stays high

Think of the brain in three layers.

At the front, you have the part involved in planning, judgment, restraint, and complex decision-making. This is the prefrontal cortex. In the middle, you have emotional processing and social reading. Lower down, you have older survival circuitry built for speed and protection.

When your business creates sustained pressure, the handover changes. Decisions start routing less through your reflective, strategic brain and more through fast survival responses. That is why you can know the right move and still fail to hold it under pressure.

It is also why smart founders so often say things like, “I know what to do. I’m just not doing it.” The issue is not always information. The issue is access to the part of your brain that can withstand pressure. Under strain, what's happening is that part of your brain goes into airplane mode!

 

Why your nervous system is business infrastructure

Most founders treat their psychology as something private. Personal. Soft. Nice to have. I do not.

Your nervous system belongs in the same category as your pricing model, delivery systems, and team structure. It is part of the operating environment in which every strategic move gets executed. If that sounds too abstract, look at the real business consequences:

  • delayed decisions

  • proposal paralysis

  • underpricing

  • scope creep

  • reactive leadership

  • founder bottleneck

  • strategic work that never gets the best of you

When your internal system is overloaded, your business starts showing it everywhere. In sales. In delivery. In team dynamics. In the way you use your mornings. That is why nervous system regulation for entrepreneurs is not wellness content. It is a commercial advantage.

 

How to regulate before high-stakes decisions

My first recommendation is practical. Regulate before you respond. When your body is in a stress response, your thinking changes. You may still sound composed. You may still look capable. But your judgment is narrower, faster, and more threat-sensitive than you realise.

One useful technique is the physiological, or cyclic, sigh. Stanford Medicine describes it as a controlled breathing exercise that emphasizes long exhalations, and reported that five minutes a day improved mood and reduced anxiety in a Stanford-led study. The related Cell Reports Medicine paper found that exhale-focused cyclic sighing produced greater improvement in mood and a bigger reduction in respiratory rate than mindfulness meditation in that trial. 

Here's how simple it is to apply the physiological sigh:

  1. Take one inhale through the nose.

  2. Take a second, small inhale on top.

  3. Exhale slowly through the mouth.

  4. Repeat for a few cycles before you make any important decisions.

It's not magic. But it is one million per cent a way to interrupt escalation and return some control to the part of you that can think strategically.

 

How to expand your window of tolerance as a business leader

Your window of tolerance is the zone within which you can remain clear, present, and responsive under pressure. Inside that window, you can price cleanly. Read the room well. Hold a boundary without becoming sharp or avoidant. Think beyond the next fire. 

Outside it, you tend to move in one of two directions. Flooded and reactive. Or flat and checked out.

The pressure of scaling narrows that window if you do nothing to offset it. Poor sleep, constant context switching, client delivery load, sales pressure, and team decisions all compress your capacity.

That is why I recommend deliberate challenge outside work. Training. Breathwork. Physical effort. Not for aesthetics. For resilience. You are teaching your system to stay coherent under discomfort so that business pressure does not immediately knock you out of strategic range.

“That wider window is a direct commercial advantage.”

 

How to protect your prefrontal cortex and stop wasting your best thinking

Your best thinking is finite. Treat it that way. This is where decision fatigue in business becomes expensive. The same brain that decides how to respond to a scope issue also decides which email to open first, what to wear, whether to check LinkedIn, and how many tabs to keep open while pretending to work.

You don't need me to tell you where this goes. By the time the strategic work arrives, your sharpest judgment has already been spent on trivia. Two fixes help.

  1. Create standing rules for recurring decisions. Define fit. Define scope. Define how you handle common situations. Decide once. Reuse often.
  2. Then protect the first part of your day. If your mornings are when your prefrontal cortex is clearest, do not donate that window to low-value reactivity. Your inbox does not deserve your best cognition.

 

Why trust starts before your words do

Your nervous system is constantly reading other people, and theirs is constantly reading you. That means clients do not only respond to your expertise. They respond to your state.

Two experts can say the same thing in the same meeting and create different outcomes. One feels steady, safe, and clear. The other feels tight, rushed, or over-eager. The content or offer might be a great fit, but because of your state, the impact may not come through as you intended.

That is why I tell founders to regulate before important client interactions, not just before difficult emotional moments. Your state enters the room first. If you want more authority, more referrals, and less unnecessary pushback, this matters.

 

Conclusion

The gap between your expertise and your results is not always a strategy problem. Sometimes it is a signal that your nervous system is carrying more load than it can currently process without distortion.

That is not a character flaw, weakness of any kind or proof that you are not cut out for the next level. It is simply a constraint. Which means it can be assessed, trained and upgraded.

If you want to scale without survival mode, start here. Identify the one commercial moment where stress is costing you most, and apply one of these practices with discipline. Not for a week. Long enough to change the system your strategy runs on.

 


 

Frequently asked questions

Can stress really affect sales performance that much?

Yes. Stress changes how you interpret risk, hold silence, respond to objections, and protect your price. That is why calm founders often sell more cleanly.

What is the physiological sigh?

It is a breathing pattern that uses a double inhale followed by a long exhale. Stanford Medicine describes cyclic sighing as a controlled breathing exercise that can reduce anxiety and improve mood.  

Is this just mindset work with a new label?

No. Mindset can help, but this episode is about the nervous system conditions that shape whether strategic thinking is available under pressure.

What is the window of tolerance in business?

It is the range in which you can stay clear and effective under stress. When that window narrows, pricing, leadership, and decision-making all become harder.

Why do I underprice even when I know my value?

Because pricing confidence can collapse under pressure. If your body reads the moment as threat, you may move to safety before you move to strategy.

How do I protect my best thinking at work?

Reduce recurring low-value decisions and guard your mornings for deep work. Decision fatigue drains the same energy you need for commercial judgment.

[00:00:00] Why your strategy may not be the real problem  

[00:00:00]  

[00:00:00] Deirdre Martin: Here's a diagnosis. Most business content will never give you. There is nothing wrong with your strategy if you're stuck. What's keeping you stuck is the nervous system executing your strategy has not been upgraded to meet the stage that your business is at. And I mean that literally, not as a metaphor, some kind of motivation as neuroscience. 

The part of your brain that controls how you think, how you react, how you perform under pressure, it is literally running on old software, early stage software, software that was built for survival, not for skill. And every decision that you make under pressure, every proposal conversation. Drifts every strategic priority that keeps getting displaced. 

That's not a willpower problem. That is quite literally your biology doing exactly what it was built to do in the wrong context and at the wrong cost. So let me show you four specific ways to fix this. 

[00:00:58] The 3 layers of the brain and what scaling pressure does to them 

[00:00:58] Deirdre Martin: Okay. First we're gonna [00:01:00] talk about the problem underneath the problem, and this is where I'm gonna show you the actual mechanism because understanding this. Properly changes everything. Think of your brain as having three layers. So the front part, just behind your forehead, that's your thinking brain. 

Where strategy, long-term planning, the ability to hold a really complex decision and choose wisely. That's all in your prefrontal cortex, and this is your most. Valuable professional asset. The middle layer handles emotion and reading other people, and the bottom layer is your survival brain, ancient, fast, and built for one job only to get you outta the fucking way before danger comes and you know, without you even having to think about it. 

[00:01:47] How stress hijacks pricing and sales conversations 

[00:01:47] Deirdre Martin: So here is what scaling a business does. It creates chronic pressure. Sustainably, right? And when you are under [00:02:00] sustained pressure, the brain stops rooting decisions through the thinking layer, and it starts running them through the survival layer. Not occasionally or systematically, but every fricking time that the load spikes. 

And I want you to feel this rather than just understand it. I want you to think about the time that you were on a call with a really strong prospect, someone who was an absolutely great fit for you, where your offer was within their budget, and they were the kind of client where you're going, oh, I would love to work with them. 

And somewhere in the conversation they paused. Maybe it was at the price or when you asked for a decision or maybe they asked you to justify the investment, or maybe they just went quiet. And before you'd consciously decided anything, you started softening. Filling the silence, adjusting the number, and maybe even trying to offer in and build in more value than you'd planned to. 

[00:03:00] Not because you chose to, but because literally your survival brain read their hesitation as danger and went, oh shit, and started responding before your thinking brain. Even had a chance to get a vote in there, and that's nothing to do with your confidence. It really isn't. It's nothing to do with your ability to be able to sell. 

That is quite literally your biology making a commercial decision on your behalf, and it is happening across. Every high stakes moment in your business. Proposals, pricing, boundaries, complaints, strategic planning, that gets pushed aside because there is nothing left in the brain tank for it. And in scaling businesses, that is happening consistently, unfortunately, at a compounding cost. 

[00:03:49] Treat your nervous system like business infrastructure 

[00:03:49] Deirdre Martin: So. Here's the frame I want you to take from this video. Stop treating your psychology as something to manage around and start treating your nervous system as infrastructure. [00:04:00] Same category as your pricing model, your delivery system, your team structure, your marketing, whatever it is that you have. And when you think about it like infrastructure, then it can be assessed, identified as a constraint and deliberately upgraded because the experts who consistently attract high value clients, the ones who are able to hold their prices in those conversations and build businesses that actually reflect their capability. They're not just better at marketing. They're not. They're not better than you. They just operate from a different quality of internal stability. Their thinking is clearer. Their decisions then can become more precise, and they show up to important moments in a fundamentally different state. 

And that's nothing to do with how much. Better than you that they are, because they're not. It's nothing to do with their personality, it's just something that they built. 

[00:04:58] Regulate before you respond  

[00:04:58] Deirdre Martin: And here's [00:05:00] how hack number one regulate before you respond. When your body is in a stress response, your cortisol elevates, and then your survival brain kicks in. 

The thinking front of your brain is not working properly. By which I don't mean it's struggling or it's slowed down. It's quite simply offline, like airplane mode essentially. Which means every high stakes decision made in that state is not your strategic brain talking. It is your threat response wearing your business language on the front end. 

So the fix is a regulation practice before any decision that matters before pricing conversation. Before a difficult client call basically before any strategic choices with real consequences. And the fastest science backed method that I've come across for this is literally called the psychological sigh. 

And how it works is you take two short inhales through [00:06:00] the nose, stacking one breath on top of the other, so you top it up. Followed by one slow exhale through the mouth. And a researcher, Andrew Huberman at Stanford, he identifies this as the fastest known way to shift the body from a stressed state into a clear, calm one in seconds. 

And how it works is you do four to six cycles of that, and it literally takes. Less than 30 seconds. So the decisions that you can make after those 30 seconds is totally neurologically different from the ones that you might have made without them. And this is not. Theory, my friends, this is biology. So for an expert whose business runs on the quality of their judgment, this is the highest return habit available. 

It costs nothing and it protects everything. Psychological sigh. Ah. 

[00:06:55] Expand your window of tolerance 

[00:06:55] Deirdre Martin: Okay. Hack number two, expand your window of [00:07:00] tolerance. Think of your ability to stay calm and clear under pressure as a window. Inside the window, you have full access to your thinking brain, your strategic patients, your ability to read people, and you're fully functional and you're so fully yourself. 

What happens is too much pressure actually pushes you above it, which results in your brain becoming flooded, reactive, and unfortunately making snap decisions or snapping at people that you will later regret too little below it. And you're essentially me checked out and going through the motions, right? 

Here's what building a business does to that window. It narrows it because you are experiencing sustained stress, possibly less or disrupted sleep than you need and deserve. And the constant mental cost of switching between delivery, sales, team issues, strategy sometimes in the same hour. 

Each of these progressively compresses the zone where you're. Actually at your [00:08:00] best. So the business and your capacity to handle it actually shrinks. And at the exact moment where the business needs your most sophisticated leadership, you have less of it available. So the fix here is not to remove the pressure because that's never going away. 

Let's be real. But it is to expand your window, and you do this through regular deliberate physical challenge. Outside of work hard training. I'm talking like pushups, you know, what's the stuff it's called? I wanna say? Yeah, like hit sessions, all that sort of stuff. Plus breath work that pushes you slightly past your comfort zone. 

Yes, for sure there are fitness benefits, but the purpose of this is actually nervous system training, teaching your body through repetition that it can handle discomfort without losing clarity. That capacity transfers directly into how you function when a client pushes back at the wrong moment, or when a hard decision lands [00:09:00] on a bad day, and we all have those. 

So when the business gets complicated and fast at the same time, that wider window is a direct. Commercial advantage and almost nobody is building it deliberately. Like, what the fuck? 

[00:09:15] Protect your prefrontal cortex 

[00:09:15] Deirdre Martin: Okay, hack number three, protect your prefrontal cortex. Your thinking brain has a daily energy budget. Literally think of it like the battery on your phone when it's an overdrive. 

When you've got too many tabs and windows open, the battery trains faster, and this is the part that surprises most people, which surprises me, is that it gets just as depleted deciding which email to open. First in the morning, what LinkedIn post a comment and whatever it is that you do first thing in the morning as it does making an important strategic decision. 

So every small decision pulls from that same pool. So by the time most experts reach the work that actually needs their clearest thinking, they have already spent a significant portion of their thinking [00:10:00] budget on things that didn't require it. Barack Obama, he used to wear the same suit every day. Steve Jobs, he wore the same black poloneck every day. 

Simon Cowell, white t-shirt, and jeans for decades, right? This is not an example of minimalism at its finest. It is literally cognitive resource management. Ha. Just realized that's a different kind of CRM, cognitive resource management. So removing low value decisions from a system that they understood to be finite and precious. 

What that does is it literally helps you preserve. Your brain power. So two things you can do immediately. First, build standing rules for anything that's recurrent. Anything, what clients you wanna take, as in, are they the right fit? And build standards for that. What your scope boundaries are. So have your proposals. 

Know what scope is gonna be included, how you respond to common [00:11:00] situations or frequently asked questions. Decide those once. Do them in advance because these never again will ever need to draw on your daily brain budget. Second, protect your mornings for 99% of people. Your thinking brain is sharpest before the day's load is accumulated. 

Most experts hand that window to their inbox. Like what? Or LinkedIn and what that ends up doing is pulling the brain into reactive mode before the important work has started. So like tell me here, what is the first thing that you reach for in the morning? Let me know genuinely, because the answer is diagnostic. 

It tells me what your best thinking window has currently been spent on. 

[00:11:47] Why social synchrony shapes trust and authority 

[00:11:47] Deirdre Martin: Hack number four, master social synchrony. Okay. Your nervous system is in constant automatic conversation with the nervous systems of the people around you. Okay? [00:12:00] Before words. Social media strategy, any of that stuff. We evolved as social animals whose survival depended on being able to read other people fast. 

So your body is doing this in every interaction, even when it's online. You're scanning the people across from you for signals, whether they're safe or dangerous, whether you feel calm or threatened, whether they're trustworthy or not. And the people that you work with are literally doing the exact same thing to you. 

When you arrive at a client interaction carrying the stress of maybe a difficult morning, an unresolved problem, professional or personal, or a tense call that just ended your client's body picks that up before you have said a word. And instantly what will happen is their guard will go up, their openness will close down, and the quality of the conversation that potentially you could have had will shift. 

And it's nothing to do with what you've [00:13:00] said. It's because of the state your nervous system is in. When you arrived. That's it. And most experts prepare for important interactions by focusing entirely on content. The talking points that they're about to have in the conversation, the likely questions, how they're gonna position their offer. 

And yes, 100% that preparation matters. But content is the second thing a client evaluates. The first is whether being in the room or even on Zoom with you, feel safe, clear and trustworthy, and two experts could show up and literally deliver the same strategy in the same meeting and produce completely different results, which is nuts because the state that they walked into the room was just different. 

And the experts who get referred without asking the ones who are retained without having to justify their value. The ones who are trusted with the most important work, they're not always the ones with the most polished presentations. They're the ones whose internal state [00:14:00] matches the authority of what they're saying. 

So the fix here is simple. Two minutes before any important interaction regulate, get clear because your state enters the room before you do every fricking time. 

[00:14:14] The consultant case study, what changed in 8 weeks 

[00:14:14] Deirdre Martin: So here's what this looks like in practice. A client I was working with is a consultant and she had a really highend advisory practice. 

Absolutely so excellent at what she does get an incredible results for her client and genuinely clear on her positioning, but every time business pressure peaked for her because of delivery, demand and pipeline management. What ended up happening was her commercial decisions deviated from her own standards, so she would send out proposals that she underpriced and like knowing one, she was doing it and then kicking herself later. 

Scope creep was a regular thing because the boundary felt riskier than absorbing the work. The business development activity [00:15:00] that would've compounded her authority kept being displaced by reactive client management. Essentially, she was just drowning in work, and when we mapped the pattern, what it was. 

The problem actually became really pretty obvious was that the decisions that cost her most were almost always made when she was feeling under high stress and there was nothing wrong with her strategy. What was happening was the stressed version of her brain was simply overriding it. So we built a short regulation practice before high stakes commercial interactions for her. 

She started to restructure her mornings. She delete LinkedIn off of her phone. She started with three short PT sessions a week for basically just for her nervous system expansion. And within eight weeks, the decisions changed. She started holding fast with her pricing. Her boundaries literally functioned as boundaries as they should. 

And the business development work began happening again because [00:16:00] the mental energy for it was no longer being consumed by basically damage control and. Doing the client delivery stuff and some of the busy work that was actually just literally busy work and then the business did not get less demanding. 

But what happened was she got more capable of handling it better, and that is what treating your nervous system as infrastructure actually produces, and it's so essential when you're actually in the middle of scaling your business. 

[00:16:27] The 3 mistakes that keep founders stuck 

[00:16:27] Deirdre Martin: So three things that will kill your progress with this. One is treating this as optional wellness content to revisit when the business is quieter? 

No. What I've described today is the system your strategy runs on, it matters the most when. Your business is at it's most demanding two. Inconsistency, two weeks of practice. Then abandonment. Your nervous system builds true repetition just like every other muscle in your body. Consistent and repeated. 

Consistent and repeated. Treat these [00:17:00] with the same non-negotiable. You give any system your revenue depends on three strategy before state. Going straight from a stressful interaction into your most important work is a no-no. The stress does not resolve because you've opened a new document or you're speaking to a new client. 

So sort out your state first and then strategy second, not as a preference, as the condition under which you know your best thinking is actually available to you. 

Okay. Here's three things you can do to help you with this right now. First name, the one commercial moment in your business where a stressed brain is costing you the most specifically. Is it when you're having pricing conversations or you know you're setting boundaries around what the work is gonna be? 

Or is it the strategic work for working on your business that keeps getting deferred by to something else or gets put off entirely? Because that is where your first practice belongs. So pick one [00:18:00] hack and apply it there with genuine consistency, just one. And again, remember, repetition is the goal. 

[00:18:06] What to do in the first 90 minutes of your day 

[00:18:06] Deirdre Martin: And another thing then to do is look at your first 90 minutes of every morning. What are you actually doing to the quality of your thinking that you bring to work each day to your business each day? And for experts whose primary asset is their thinking. And most of the clients I work with, their consultants, coaches. 

Expert service providers, your thinking and your brain is the highest leverage question on the table right now. So if you've been recognizing your own patterns in this video, here's what I want you to do. Subscribe. Because this is what I build here. Not generic business content work specifically for serious experts who are closing the gap between the quality of their expertise and the business that's meant to reflect it. 

And the video I've linked below takes this even further. The strategic layer, how we translate the [00:19:00] internal clarity we've talked about today into positioning and messaging that makes the right clients choose you. That's the next piece. It's right there. 

The gap between the expert you are and the business you're building is not a strategy problem. It's a signal, and now you know where to look. Until next time, keep mastering your business.
