Here are a 100 Tips for a Better Life from the site LessWrong. It’s fun and insightful. For example:
43. Deficiencies do not make you special. The older you get, the more your inability to cook will be a red flag for people.
48. Keep your identity small. “I’m not the kind of person who does things like that” is not an explanation, it’s a trap. It prevents nerds from working out and men from dancing.
53. To start defining your problems, say (out loud) “everything in my life is completely fine.” Notice what objections arise.
Take a look at all 100. Better still, pick three that you might apply to yourself and try them out. You might find by next week your life has gotten better.
