I feel amazing right now. I just feel like dancing.

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.

One of the most difficult things to give away is kindness, for it is usually returned.

Just for the record, saying 'The surprise hasn't started yet' while pulling something out of your pants is super creepy.

What, to many, passes for thought, is usually a compound of prejudice, desire, and whim.

Life is too short to stress the small things anymore.

I've been a religious, spiritual person for a long time.

Its who you know and who can help you.

Honestly, I don't read newspapers, magazines, whatever. They're just not part of my lexicon. I don't want to be manipulated, or manipulated about other people's work.

I can honestly say it took two full years for me to get over the fact that I was no longer a baseball player.

How dreadful knowledge of the truth can be when there's no help in truth!

Know thy enemy and know thy self and you will win a hundred battles.
