Post-Exit Brain Chemistry: Re-Ignite the Drive (Dopamine)

An exit isn’t just a financial event. It’s a storm inside our brain.

For years, we live on edge. 

Every milestone, every setback, every near-death moment with the company pushes our system into overdrive. 

Our 4 key brain chemicals - dopamine, cortisol, oxytocin, and serotonin - work around the clock to carry us through the extreme startup marathon:

• Dopamine surges to fuel the hard work.

• Cortisol keeps us focused under stress.

• Oxytocin sustains team effort and leadership.

• Serotonin struggles to keep us sane while survival and success come first.

And then, suddenly… it’s all over. 

The business is gone. The years of marathon abruptly end. Our brain chemistry collapses into chaos.

In this series, we’ll explore exactly how an exit affects the brain. 

We’ll look at each of these precious molecules: how they react to an exit, what that means for us, and most importantly, what we can do about it.

Let’s start with dopamine.

The Dopamine Tsunami

Dopamine is a molecule of pursuit. Our brain releases it as soon as we want something, to fuel the chase.

As we push toward the exit, dopamine doesn’t just rise, it builds into a tsunami. 

And after an exit the wave breaks, flooding our system.

For some of us, the crash comes almost immediately after an exit. Instead of satisfaction, we’re hit hard by disappointment and emptiness.

But for most of us it plays out differently. First, the exit indulges us with a period of exhilaration: excitement about the wealth and pride of the achievement.

That high typically lasts for up to 6 months. But eventually the tsunami breaks. 

That’s simply how dopamine works: a trough always follows a peak. 

A small spike, like a square of chocolate, a praise, a point won on the tennis court, returns our dopamine level back to baseline within minutes. 

But a massive, extended surge plunges us way below the baseline. The higher and longer the wave, the deeper and longer the trough.

An exit is the biggest wave of all. Which means the aftermath can feel like demolition.

The high collapses into silence.

Confusion overwhelms.

Self-doubt creeps in.

Drive vanishes.

Energy drains. 

Not for minutes. For months, sometimes years.

The Key Lessons 

In my 15 years of studying the post-exit phenomenon, I’ve seen the same pattern repeat. The dopamine crash is real. 

And there are 5 key things we need to know about it:

• Nothing is wrong with us. This is the natural physiology of a human brain after a massive high.

• The trough is temporary. It feels endless, but the system does reset.

• We are in charge. Balance can be restored if we know how to work with it.

• It doesn’t need to last years. With knowledge and discipline, we can recover far faster than if we simply wait it out.

• A life-changing opportunity. While rebuilding, we can learn to influence our emotions and energy levels - a truly powerful skill!

And what if we refuse to take responsibility?  Then, the risks are very real.

I’ve seen it too often. 

About 10% of highly successful exited founders - people who have everything - choose to reach for dangerous dopamine fixes. 

Alcohol. Drugs. Porn. Infidelity. Buying love and friendship.

What begins as a quick escape from the crash turns into addiction, broken families, bankruptcies, even serious mental health collapse. 

Many never recover. For others it takes decades.

It’s a risk we must avoid. And luckily, we can.

How to Restore Dopamine

Here are the tools that help us raise dopamine levels during the post-exit trough and restore a healthy baseline:

• Mastery. Our brain rewards structured novelty and effort with dopamine. New challenges and new skills - chosen deliberately, not chaotically - deliver dopamine lifts without the crash.

• Movement. Exercise naturally boosts dopamine. But the gain depends on attitude. If we enjoy the movement, the dopamine rise is big. If we hate it, there’s almost none. Learning to love the activity itself, not just the result, makes dopamine sustainable.

• Sleep. Years of founder life often wreck our sleep. But sleep is when dopamine receptors reset. Without it, the trough deepens.

• Deep rest. Ten or twenty minutes of non-sleep deep rest — eyes closed, guided, fully relaxed but awake — restores dopamine sensitivity and calms the nervous system.

• Food. Dopamine is built from specific raw materials: protein and tyrosine-rich foods: salmon, chicken, eggs, turkey, almonds, bananas.

• Water. Water with essential micronutrients support the brain’s dopamine pathways: they don’t spike it directly, but give the system the fuel it needs to function. 

• Caffeine. With caffeine, the timing matters: a single cup earlier in the morning, about 60 to 90 minutes after waking, boosts mood by enhancing dopamine signaling. But taken too early, it can blunt natural cortisol rhythms or impair sleep later. Smart timing gives us the benefit without the downside.

• Meditation. Regular practice strengthens attention and helps regulate dopamine over longer horizons. I aim for 20 minutes twice a day.

• Cold exposure. A short plunge or cold shower gives a clean, hours-long dopamine lift. The afterglow is long, stable, and exactly what we need in recovery.

• Music. One of the strongest dopamine triggers. It can light us up instantly.

These practices work but only if we avoid training our brain the wrong lesson.

A Common Trap

After an exit, many of us try to shift from chasing external motivators — money, status, winning the game — to cultivating intrinsic motivation: the pure satisfaction of learning, creating, or mastering something new.

This shift is vital. Most of the old drivers no longer sustain us - our exit already satisfied the hunger. 

And even when money or status still excite us, they cannot produce the deep, lasting fulfillment we crave post-exit. For that, we need to be pulled by genuine love of the activity itself.

But in that transition, it’s easy to fall into a trap: to accidentally train our brain to release dopamine in response to the external reward instead of the activity itself. 

This sabotages our effort to find intrinsic motivation. The work then feels like work. And the moment it gets hard, we quit.

It usually happens in 2 ways:

1. Quick Hits 

We start something new, maybe testing a new business idea, writing, teaching or philanthropy. 

But it comes with some form of quick dopamine hit - like comments on our social posts.

Without realizing it, our brain begins to link dopamine not to the work, but to the external spark. 

When isn’t there, the work feels flat. We lose interest. 

We walk away before it has the chance to grow. 

2. External Rewards

We try to build new habits, and the common advice is: reward yourself for every small step.

And yes, it works. Dopamine spikes. Briefly.

But the price is high.

We stop linking joy to the activity itself. The pleasure shifts to the external reward.

Soon the habit feels like a chore. And when it gets hard, we quit.

So what’s the alternative?

We train dopamine to rise from the effort itself.

Neuroscience shows we can condition the brain this way: in the hardest point of a challenge, we tell ourselves: I like this. I choose this.

It feels unnatural at first. But it works:

• Our brain releases more dopamine, because the amount depends on how we feel about the effort in the moment. 

• The effort starts feeling easy and rewarding, so we are likely to keep doing it.

• Dopamine provides energy to support the chosen activity - reliably and sustainably.

• It shifts our motivation away from external rewards and toward an intrinsic drive.

By shifting that signal, we retrain the system to reward the work itself.

Post-exit, this shift - from reward-seeking to effort-loving - may be the single most valuable skill we can master. 

Because whatever comes next, whether it’s a new venture, a creative pursuit, or public service, we want it to feel rewarding in itself. 

Otherwise, our second act risks becoming just another job. Otherwise, we are too likely to quit.

Supporting What’s Next 

The exit gave us a dopamine surge of seismic force. The trough that followed can feel like devastation. 

And it may last for years.

Our task is not to chase another peak. It’s to rebuild wisely. 

To restore balance through rest, food, exercise and new challenges and skills.

To train our brain to love the activities that are good for us and reliably generate energy to support them.

Because mastering our own chemistry is one of the indispensable post-exit skills. 

Without it, we risk self-destruction. We risk never finding a new purpose. We risk never building real fulfillment.

But if we master our chemistry, we get our drive back. We control our energy. 

We have sustainable fuel for whatever we choose to do next.

In my next article, I’ll examine another molecule critical to our post-exit well-being - serotonin.
