Reputation is often discussed as something you manage, something you craft, something you protect. Social media has turned this into an industry. But this is a fundamental misunderstanding of what reputation actually is. A managed reputation is not a reputation. It is a performance. And audiences, even without knowing exactly why, can tell the difference. Your real reputation is the accumulated experience of every person who has ever dealt with you. Not your intentions, not your self-presentation, not your best moments: the totality of encounters, especially the ordinary ones, especially the ones that cost you nothing if you cut corners. The colleague who watched how you handled a mistake. The friend who saw how you treated someone who could do nothing for you. The person who was in the room when you thought it did not matter. These experiences accumulate. They form a picture. And that picture is your reputation whether you know about it or not. The implication is important: reputation cannot be manufactured. It can only be built or eroded by how you actually behave. The person who understands this stops asking how do I manage my reputation and starts asking who am I when no one is watching? That is the question with actual leverage.
