"Without a way out, you would not be able to find your way in."

Written by someone brilliant at his craft...But the story's been taken down. Recently this phrase has been coming back to me over and over again.

It's true though. If there's no way out, no matter how tedious or agonizing, I would not be able to go all the way in. But if I have a parachute, I have the courage to fly.
