Some achievements feel empty because reaching them answered a question you never actually cared about.

Reaching a goal that was never really yours produces a distinctive flatness, because the achievement answers a question you were not asking. Usually the goal was inherited, from a parent, a field, a period of comparison, and the emptiness at the end is the first honest information about it.

When a success feels hollow, treat that as data rather than ingratitude. Ask whose question you were answering. The next goal is worth choosing more deliberately than the last.
