Your phone charges daily. Does your brain?
Mary Miller calls it the entrepreneurial time system: a full day, midnight to midnight, with zero business thinking allowed. Not a vacation. Not a half-effort weekend where you still check email. It's a hard boundary that protects relationships, health, and clarity, because the moment business thinking creeps back in, the recharge stops working.
We plug our phones in every night without a second thought. Our brains get no such courtesy, and that's the problem.
