If you want to enjoy life, never worry about the mundane or waste time talking about trivia or obliging social conventions. Those are the traps to avoid.
Take care of the basics - healthy food, exercise, sleep, few strong friends, and beyond that live in the delusion of great dreams and ideas. Read incessantly, write and express, argue and debate. Never worry about realizing dreams and ideas. They are dreams and ideas, which are meant to inebriate you. If they lead to something, treat it as something you never planned and shy away from credit.
Last of all, thank people if they rob your ideas. Imagine, if they did not, you would have to work to implementing them. Seeking credit or recognition is the poison that ruins happiness. Just live, let live, renounce and rejoice.
