Success means doing something sincerely and wholeheartedly.

There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.

Do not like, do not dislike; all will then be clear. Make a hairbreadth difference and heaven and earth are set apart.

The usefulness of the cup is its emptiness.

To me, racial barriers do not exist in reality. If I say that 'everyone under the sun is a member of a universal family,' you may think that I am bluffing and being idealistic. But if anyone still believes in racial differences, I think he is too backward and narrow in his perspective. Perhaps he still does not understand man's equality and love.

Training is one of the most neglected phases of athletics. Too much time is given to the development of skill and too little to the development of the individual for participation.

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.
