What creates a person's character?

What makes character?

Your real self is built up by the use you make of the mind than by the use you make of the body. It is the mind that makes character—that is far more active, more potent than the body, which is but a poor instrument at best.

Hence, the thoughts and intents of the heart, the imaginations of the mind—these are the things by which the spirit is judged, for it is you who make up and create the real character of the inner self, which becomes visible after the leaving of the body.
