Age teaches which victories are not worth celebrating.

Some wins turn out to be costly: the argument that damaged something, the promotion that consumed the rest of your life, the point proved to someone who now avoids you. Age teaches you to look at the whole ledger rather than the score.

When you next win something, ask what it cost and whether you would pay that again. Occasionally the honest answer is no, and noticing that is what stops you from chasing the same kind of victory repeatedly.
