“Be the best at what you're good at”
“The Enemy of the best is the good. If you're always settling with what's good, you'll never be the best.”
“The best way to get something good out of what you're doing is to put something good into it.”
“You're not very good at this, are you?''At what I do, I'm the best. This isn't what I do.”
“You're as good as the best thing you've ever done.”
“The best years are when you know what you're doing.”
