Your reputation is how your friends describe you to someone who’s never met you.

Reputation lives in other people’s mouths, not in your own head. You cannot sit a stranger down and explain yourself; what reaches them is one sentence from somebody who knows you, delivered in a hallway. That sentence is built out of how you treated your friends over years, not out of anything you have ever said about yourself.

Think about what your two closest friends would honestly say about you in that sentence. If it is not what you want, the fix is in how you behave with them, not in managing the message. Ask one of them what they would say, and listen without arguing.
