1) You should be constantly surprised. If you're not, you live in an echo chamber. No human gets it all right immediately, and learning to get it right happens slowly and in pieces. Seek surprise, seek outrage, seek humbling. If you don't periodically experience one of those, you aren't being exposed to the true spectrum of humanity and life out there.
2) You are partly a shitty person
and/or
You are partly a good person
depending on which perspective you start out with.
3) Bad stuff doesn't last forever. Your moods are not reality.
4) With most of what you think, the opposite is at least partly true, including 3). You are a sack of decaying shit who doesn't know much. Accept it graciously you fucking asshole.
