Being brave once is a story. Being brave daily is a reputation.

One act is a story people tell. Repeated small ones change what people expect of you, and expectation is a different kind of thing: it alters what you get asked to do, who comes to you when something goes wrong, and eventually what you assume about yourself. A reputation is really just a prediction other people have started making.

Pick one small version you can do every day this week. Saying the awkward true thing, asking the question in class, making the call you would rather text. Daily is the part that matters.
