Saying yes to everything means breaking promises on a schedule. Learn to say “I can’t take that on.”

Every yes is a booking, and there is a fixed number of hours behind them. Agree to enough and the failures start arriving on their own timetable, one let-down person at a time, none of which you meant. The yes felt generous in the moment. What arrives later is the opposite, because now someone was counting on you.

Before the next automatic yes, look at the actual day it lands on. If it is already full, say you cannot take that on, with no long excuse attached. People remember a clean no far more kindly than a yes that fell through.
