First off: Reputation, Posterity and Cool are traps. They’ll drain the life from your life. Reputation, Posterity and Cool = Fear.
Let me put that another way. Bob Hope once said, “When I was twenty, I worried what everything thought of me. When I turned forty, I didn’t care what anyone thought of me. And then I made it to sixty, and I realized no one was ever thinking of me.”
From Patton Oswalt
