The hidden cost of high performance

2024 was the biggest year of my career.

Record numbers. Major wins. The kind of performance you’re told to chase. From the outside, it looked like my best year yet, and in many ways, it was.

Inside, it felt nothing like success.

I was tired in a way that sleep couldn’t seem to fix. Stress had become background noise. I was losing sleep thinking about decisions, moving through my days on drive and discipline more than energy. Small things took more effort than seemed reasonable. My body felt depleted, but I kept going because that’s what high performers do.

Nothing broke. I delivered everything I was responsible for. If anything, I became more efficient, more focused, more contained.

But by the end of that year, I wasn’t energized by the results. I was exhausted by what it had taken to produce them. It was clear I couldn’t keep operating that way, even though no one on the outside would have known.

So instead of setting a bigger goal for the next year, I stepped away. I created a three-month sabbatical for myself.

Not to escape, and not because I was done. I stepped away because I wanted to come back able to lead well, not just keep pushing through. During that time, I rebuilt the basics that had quietly eroded. I found real sleep, health, space to think, boundaries around my energy. I remembered what it felt like to have capacity again.

What surprised me most was how quickly clarity returned once the constant pressure stopped. I didn’t come back less driven. I came back unwilling to trade my well-being for performance that couldn’t be sustained.

This experience changed how I think about leadership. My presence was restored. My capacity expanded to lead differently.

Burnout at senior levels rarely looks dramatic. It looks like leaders are still functioning. Still delivering. Still carrying responsibility. That’s exactly why it’s precarious, success can hide the cost. The leaders most at risk aren’t the fragile ones. They’re the capable, reliable people who can absorb pressure for a very long time without dropping the ball.

But absorbing pressure isn’t the same as being resourced.

Just because you can keep going doesn’t mean the way you’re going is sustainable. And leaders don’t just shape results, they shape the conditions under which those results are produced. When exhaustion becomes normal at the top, it spreads. When sustainability becomes the standard, that spreads too.

My “best year” taught me something no leadership training ever had: success that costs your health, sleep, and capacity to enjoy your life isn’t real success. It’s deferred recovery.

The leaders who endure aren’t the ones who can push the hardest. They’re the ones who learn how to perform at a high level without abandoning themselves in the process.

If you’re quietly running on fumes while everything still looks successful from the outside, you’re not alone. The question isn’t whether you can keep going. You probably can.

The question is whether you want to keep succeeding in a way you’ll eventually have to recover from or build a way of leading that you can sustain for the long term.
