Don't fear failure. Not failure, but low aim, is the crime. In great attempts it is glorious even to fail.

Learn it all, then forget it all.

You must have complete determination. The worst opponent you can come across is one whose aim has become an obsession. For instance, if a man has decided that he is going to bite off your nose no matter what happens to him in the process, the chances are he will succeed in doing it. He may be severely beaten up, too, but that will not stop him from carrying out his objective. That is the real fighter.

Never trouble trouble till trouble troubles you. I'll not willingly offend, nor be easily offended.

If you spend too much time thinking about a thing, you'll never get it done.

In building a statue, a sculptor doesn't keep adding clay to his subject. Actually, he keeps chiseling away at the nonessentials until the truth of his creation is revealed without obstruction.

I don't want to do anything halfway. It has to be perfect.
