If you give me a short shot I will attack you. I'm not a baseliner who rallies. I try to get the point over with.

Some people say I have attitude - maybe I do... but I think you have to. You have to believe in yourself when no one else does - that makes you a winner right there.

I don't focus on what I'm up against. I focus on my goals and I try to ignore the rest.

Just believe in yourself. Even if you don't, pretend that you do and, at some point, you will.

My motto is: I'm alive, so that means I can do anything.

In my mind, I'm always the best. If I walk out on the court (and) I think the next person is better, I've already lost.

Of course, I want to be number one. But being happy and healthy is the most important thing.

Tennis is mostly mental. Of course, you must have a lot of physical skill, but you can't play tennis well and not be a good thinker. You win or lose the match before you even go out there.

When you lose, you're more motivated. When you win, you fail to see your mistakes and probably no one can tell you anything.

In the sports arena I would say there is nothing like training and preparation. You have to train your mind as much as your body.

If I cared deeply about what people thought of me, I probably would have never made it out of Compton, California.

Nature understands you more than you understand nature. Nature is your true mother.

All the women want to be with me, all the men want to be like me.

A man's profundity may keep him from opening on a first interview, and his caution on a second; but I should suspect his emptiness, if he carried on his reserve to a third.

You have the capability to change your life all with a simple shift in perspective

Most battles are won before they are ever fought.

Cricket is full of theorists who can ruin your game in no time.

If we have power to degrade an entire society, then we also have the power to uplift it.

When you stop thinking about yourself all the time, a certain sense of repose overtakes you.

There is a simple way to package information that, under the right circumstances, can make it irresistible. All you have to do is find it.

It appears that the English think the Japanese... are fond of opium, and they want to bring it here also.
