Success is not greedy, as people think, but insignificant. That is why it satisfies nobody.

Achievements often turn out smaller in the having than they seemed in the wanting. The promotion, the purchase, the milestone brings a brief lift and then becomes ordinary, leaving the same restlessness as before. The problem is not that success demands too much, but that it gives too little to fill the space people hope it will fill.

This does not mean ambition is pointless. It suggests looking for satisfaction elsewhere as well: in relationships, in the work itself, in meaning that does not depend on the next target. Ask what you expect your next goal to give you, and whether it can actually deliver that.
