1. Focus on positive thoughts and suppress the negatives ones. 2. Never stop learning, exploring, challenging yourself; the goal is to live an interesting life. 3. Pay attention to details; try to be prefect but accept that is not possible. Think more carefully before you act. 4. Look for your blind spots; learn not to make mistakes. 5. Your happiness should be based on improving your mind/body. Don't expect anything external to you to make you happy: not things, not others. Prisoner's dilemma means you shouldn't count on anyone else to do the right thing for you. 6. Manage expectations (yours and others). If the world doesn't work as you expect, then update your expectations.
