“Suppose I were to give you a key ring […] with a hundred keys, and I was to tell you that one of these keys will unlock it, this door we’re imagining opening in onto all you want to be, as a player. How many of the keys would you be willing to try?’
[…]
‘Well I’d try every darn one,’ Rader tells Lyle.
[…]
‘Then you are willing to make mistakes, you see. You are saying you will accept 99% error. The paralyzed perfectionist you say you are would stand there before that door. Jingling the keys. Afraid to try the first key.” 
― David Foster Wallace, Infinite Jest
