“...if you always put limits on what you can do, physical or anything else, it’ll spread over into the rest of your life. It’ll spread into your work, into your morality, into your entire being. There are no limits. There are plateaus, but you must not stay there, you must go beyond them. If it kills you, it kills you. A man must constantly exceed his level.”

“If you always put limits on everything you do, physical or anything else, it will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.”

“Death demands your attention. It requires you to think your unthinkable. It insists that you go to your dark places, those places you have so carefully learned to avoid all your life. You are pushed far beyond what you ever imagined to be your limits. You must accept your unacceptable.”

“Doubt is the thing that’ll kill you, the only thing, and it’ll kill your friends, too.”

“Something you killed didn't stay dead? Wow. That must have really put some termites in your coffin.”

“The size of your dreams must always exceed your current capacity to achieve them. If your dreams do not scare you, they are not big enough.”
