Once you've been number one, you can never be satisfied with less.

To be a tennis champion, you have to be inflexible. You have to be stubborn. You have to be arrogant. You have to be selfish and self-absorbed. Kind of tunnel vision almost.

You've got to take the initiative and play your game. In a decisive set, confidence is the difference.

Find something that you're really interested in doing in your life. Pursue it, set goals, and commit yourself to excellence. Do the best you can.

You can't give up! If you give up, you're like everybody else.

The sun rises from the two places: From the East and also from where the Science rises!

To go out of your mind at least once a day is tremendously important. By going out of your mind, you come to your senses.

I have turned down a lot of garbage lately.

I want our pie to grow all the people, but if some other guy's pie is growing a little faster, that's terrific.

I'm here instead of having shoulder surgery. But I'm not sure which is more painful.

A chef who doesn't wash his hands is like a cop who steals. It's a cry for help.

No one ever teaches well who wants to teach, or governs well who wants to govern.

I eat tons of green veggies to keep my PH balance in check.
