Your idea of yourself is usually a few years out of date. Look again.

Self-image updates slowly, and it usually froze during a hard stretch. The version of you walking around in your head may still be the one who could not speak up in class, or had no friends in a particular year, or was bad at every sport. That person existed, and the evidence has been piling up against them ever since.

List three things you believe about yourself that were formed before fifteen. For each one, look for something from the last six months that contradicts it, because there usually is something. Updating is not confidence or pretending; it is just reading the more recent data.
