... a lot more, but honestly while not all are meant to be very serious, some stuff truly helps me get by. Routine, including work, school, and chores are calming to me. Which is interesting because I dislike school and chores. Isolation makes me introspective, and long for companionship. Close friendships make me long to sail alone around the world. A beer or 6 at the end of a crazy day with nothing to do the next is incredibly satisfying. A really good amateur movie from burningcamel about every 8 weeks seems to be a guilty pleasure of mine. Helping others and making a (marginal) difference gives me satisfaction. And all my diversions such as daydreaming and the internet, are, well, diversions from this crazy life.
I dunno. It seems to be doing the trick. I experiment a little bit all the time.
