I can get angry at the drop of a hat, and I may be in the right, but my anger may not be proportionate. So for me, the action is to say sorry and explain what else happened that annoyed me. Also, it pays to fix or accept whatever made me angry.

Character is not purely an internal thing, but rather something that is built through your interactions in your environment, especially with people.

A better character is built by doing things that are challenging.
