The Choice Most Leaders Never Make — And Why Stress Keeps Winning

It's 2004. The basement of dental school. I'm standing over a cadaver with a thick nerve in my left palm, and my attending is grilling me on anatomy.

I know the right answer. I rattle it off — way too confidently, I might add — because I'd memorized the anatomy book instead of understanding it.

"Vagus nerve. Tenth cranial nerve. Longest nerve in the body. Part of the parasympathetic nervous system, responsible for heart rate, respiration, digestion, rest, restoration, healing, sir."

Textbook perfect. And I had absolutely no idea what any of it meant in my actual life.

Not until nearly twenty years later, when I started living a version of myself I didn't recognize. Not until I realized I was breathing like I was constantly running from something — my nervous system permanently primed for threat, swimming in stress hormones like that was just what life felt like.

That's when I understood what I'd been holding in my hand.

The Hidden Cost of Running on Stress

Stress is something we all carry. A car cuts us off in traffic. We're negotiating with our kids to take a shower. We're wondering if someone took an email the wrong way. We're second-guessing a decision we made three weeks ago.

But here's what most people don't realize: our bodies can't tell the difference between a threat in traffic and a threat to survival. Our nervous systems were built to respond to real danger. Instead, we're using that same response system to navigate emails, rejections, and the pressure to do more with less.

And because the stress is constant, it stops feeling like stress. It just feels like life.

This is where most high performers get stuck. They think their exhaustion is ambition. They think their panic is productivity. They think that if they're not bleeding, screaming, and crying for it, it doesn't count as success.

Most high performers have no idea they're running on chronic stress. They mistake their overdrive for their ambition.

What they don't see is what it's actually costing them.

What Happens When You're Stressed

When stress becomes chronic — when you're living in a constant state of threat — three major shifts happen.

Psychologically, your critical thinking goes offline. You fall into black and white thinking. Things are either good or bad, right or wrong, successful or failed. The nuance disappears. The creativity disappears. You lose access to the part of your brain that can imagine new possibilities or see situations from different angles. And you start making decisions from the stories your brain wrote to fill in what it didn't know — rather than from what's actually true.

Physiologically, your body releases a chemical cocktail of stress hormones. Your cells are literally swimming in this soup, and over time it becomes your new normal. Chronic stress becomes chronic dis-ease. Chronic dis-ease becomes disease. We're sicker than ever despite advances in medicine — hormone dysregulation, sleep issues, weight problems, cardiovascular issues, autoimmune disease. And we're experiencing these sicknesses at younger ages than before.

Spiritually, your ego eclipses your inner light. You stop remembering that you're inherently worthy, inherently enough. Instead, you identify with what the ego tells you: prove yourself, impress people, control the outcome, earn your worth through productivity. And that false identification leads you down a path of always chasing the next thing — waiting for the moment when you finally feel like enough. Except that moment never comes.

The Other Side: The Vagus Nerve

If the sympathetic nervous system is fight, flight, or freeze, the parasympathetic nervous system is rest, restore, heal.

The vagus nerve is the bridge. That gap — between where you are and what you're actually capable of — lives in your nervous system. And the vagus nerve is the way to cross it.

In my book, Connected: Discovering Your Inner Guides, I call it guard mode versus guide mode. Guard mode is your ego in protective overdrive — it needs to be right, prove itself, impress, control. Guide mode is your connection to Self, your inner wisdom, your remembrance that you're inherently okay.

When you shift into guide mode, your critical thinking comes back online. You can see nuance again. You can approach challenges with curiosity instead of the stories your brain wrote to fill in what it didn't know. You can lead from presence instead of panic.

And the outcomes you thought were your ceiling turn out to be your floor.

The Power of the Pause: Your Breath

The most direct access to your parasympathetic nervous system is your breath. And it costs nothing. No apps. No retreats. No special equipment. Just you deciding to slow down.

Your breath is a map. It shows you exactly where you are. If it's shallow, rapid, irregular, you're running from something — whether the threat is real or not. If it's calm, deep, regular, your body knows it's safe. And from that place, your ability to thrive through pressure — not just survive it — becomes something entirely different. Once you know where you are, the next step becomes a choice instead of a reaction.

When you slow your breathing down and get intentional with it, you're literally telling your nervous system: the threat isn't real. You can think again. You can lead again.

I've worked with clients who couldn't take a single breath before responding to a hard situation. Slowing down felt genuinely unsafe. But the second they started practicing, the second they understood that pausing wasn't falling behind — something shifted. Decisions got clearer. Communication improved. Energy stopped leaking out of everything.

Like any neural pathway, the more you use it, the stronger it becomes. It stops requiring willpower. It becomes second nature.

Why This Matters Beyond You

You've probably noticed that one person can shift the energy of an entire room. The person who walks in so heavily critical that it takes the wind out of everyone's sails. Or the person who walks in connected to themselves — calm, curious, present — and pulls everyone up with them.

That's our wiring to reflect the social behavior around us. And that's why your nervous system state doesn't just affect you. It affects everyone you lead.

If you're operating from a dysregulated nervous system (your sympathetic nervous system), your team feels it. They mirror it. Psychological safety drops. Creativity disappears. People stop bringing their whole selves to the work. Nobody names it — but everybody feels it. And it shows up not just in your retention numbers about eighteen months later, but immediately when you go home to your family and find yourself racing to put the kids to bed instead of enjoying them for who they are.

But when you're operating from the parasympathetic state — when you're in guide mode — communication opens up, trust builds, and the quality of thinking in the room becomes something entirely different. Not because you suddenly have more time or fewer problems. But because you're leading from presence.

Start Here

The next time you're up against something — a challenge, a conflict, a moment where your ego wants to assert control — pause. Notice your breath. Don't try to change it. Just notice it.

That observation alone is powerful. It tells you where you are. And once you know where you are, the next step becomes a choice instead of a reaction.

Take a breath. Feel what that's like. And then ask yourself: what would it look like to lead from here?
