“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.”

“...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.”

“you only know yourself when you go beyond your limits”

“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.”

“If you must doubt something, doubt your limits”

“They say you should know your limits and work within them. But how can you really know your limits unless you try to expand them?”
