“You are not a mistake. You are not a problem to be solved. But you won't discover this until you are willing to stop banging your head against the wall of shaming and caging and fearing yourself. (p. 84)”

“You have to bang your head against a bigger and stronger wall to realize that you are not the strongest in the world!!!”

“Clearly the secret of happiness...is a variation on the general principle of banging your head against a wall, and then stopping.”

“If at first you don't succeed try, try, try again, and if that doesn't work stop banging your head against the wall before you crack it, and try another approach. Perseverance is more than stubbornness, it's savvy.”

“If you’re not stubborn, you’ll give up on experiments too soon. And if you’re not flexible, you’ll pound your head against the wall and you won’t see a different solution to a problem you’re trying to solve.”

“It's like banging my head against the wall, except if I were actually banging my head on a wall, I'd be able to make myself stop.”
