Feynman's entire approach to life seems to be to "play" with it. He's an expert troll, the original pick up artist, nobel prize winning physicist, guest biologist, expert safe cracker, computer programmer, etc. His stories are fantastic, and a reminder that life is a ride. You should enjoy the ride, above all else.
