Ambitious People Don't Need to Slow Down. They Need Capacity.
On why the advice to slow down misses the point, and what building headroom actually looks like.
People with good intentions say you need to slow down.
"You're doing too much."
"You're going to burn yourself out."
It hits a nerve because you can feel a disdain for them erupt just below the surface, which you manage to hide this time.
You don't like them interfering, but you really don't like the fact they could be right.
You've been here before and know too well that your current rate of work will lead to a crash.
Your body is holding on by a thread.
And crashes, for you, mean months of putting yourself back together while wrestling with the sense that loved ones have stopped believing in you.
You're feeling like a bad person for not being present with friends and family.
They roll their eyes when you talk about work.
That cuts deep.
But your people are wrong.
High-output humans like you don't need to slow down.
The best build capacity.
Why would you want to slow down?
That ambition, that discipline, that motivation is gold.
It's what gets shit done.
And if we could bottle it, neither of us would be having this conversation.
What you do need to do is build more headroom to operate in.
F1 cars don't race around your local warehouse go-kart tracks. There's no room.
They fly around large courses designed to give them space to perform.
Your capacity to perform comes from the hard decisions you make around your health.
A good night's sleep: more capacity. A poor night's sleep: less capacity.
The more headroom you have, the less likely you are to flip your lid.
You know the moments I'm talking about.
Snap at your kid. Get annoyed by an email. Be rude to a stranger.
Life doesn't change.
You do.
Capacity is earned off the track.
