Every yes is spending a no on something else. Know what you’re trading.

Time is fixed, so agreeing to something is also quietly declining everything that would have occupied those hours. The yes is visible and the cost is not, which is why calendars fill with things nobody quite remembers choosing. You are not deciding whether something is good. You are deciding what it is worth more than.

Before accepting the next commitment, name out loud what you are giving up for it, in actual hours and actual plans. If you cannot name it, you do not yet know what you are agreeing to. Try saying no to one thing this week purely to see what the hours were worth.
