You already know
something needs to change.
The question isn't whether you're performing. The question is — are you ready to measure what it's costing you?
Your sleep isn't recovery — it's collapse. Your "edge" has started to feel like friction. And somewhere between the quarterly review and the performance review, you stopped trusting your own body to keep up.
This isn't weakness. This is what happens when you've been running the same engine at full throttle for 26 years — without ever checking what's left in the tank.
This is not a willpower problem. It's a capacity problem. And capacity — for the first time — can be measured.
