“You still don't know what you do well.”

“Sometimes you sit around
Don't know what to do,
don't know where you're going to
All you have to be is you
What else can you do”

“If you don't know everything, you must go on with what you do know.”

“Doing what you do well is death. Your duty is to keep trying to do things that you don't do well, in the hope of learning.”

“It's important to know what you don't want, but it's vital to know what you DO want.”

“There is no such thing as duty. If you know that a thing is right, you want to do it. If you don't want to do it—it isn't right. If it's right and you don't want to do it—you don't know what right is and you're not a man.”

“Character is doing what you don't want to do but know you should do.”

“Intelligence is what you use when you don't know what to do.”

“What's worse…?
The devil you don't know… or the devil you do?”

“Wealth means nothing at all if you do not know, to the last penny, what your fortune is. You might as well be poor if you do not know what you have.”
