Tennis is a huge part of my life, but I don't base my self-value or my self-worth or the quality of my life on my results on the court.

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.

The sooner you answer the question, "who am I" the more effective and successful life you will have

Mark Twain once said that history doesn't repeat itself, but it does rhyme.

He who would rule must hear and be deaf see and be blind.

I don't approve of sunbathing, and it's bad for you.

Tell me a fact, and I'll learn. Tell me a truth, and I'll believe. But tell me a story, and it will live in my heart forever.

My whole experience into the sitcom world, it was, like, "This is like theater, this is like film... This is a hybrid of everything I love to do. A live audience and rehearsals and... more food!"

Stains are even worse when you're the only one who can see them.

Actually I am very glad that people can buy Armani - even if it's a fake. I like the fact that I'm so popular around the world.

Sometimes you have to stop thinking. Sometimes you shut down completely. I think that's true in any creative field.

Though I may not flow where the wind guides me, I won’t become still water.
