If you close the laptop and your mind keeps going rerunning the meeting, drafting tomorrow's first email, scanning for the next thing to fix you already know the feeling. That isn't the kind of tired sleep repairs. It's overstimulation. Still running. Still on.
Hundreds of small decisions stack up over a day, and by evening the part of you that chooses is worn smooth. Forcing it to rest doesn't work. You lie down and the ceiling turns into a screen. You scroll, and the noise just changes channels. What an overstimulated mind needs isn't less. It's something smaller to run on.
