When you step out on the court, I don't think anybody thinks about age. Because if you're out on this tour it means you deserve to be here. You've got the skill. It must mean you know how to play.

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.

Encourage yourself that you are good enough to be the owner of your own storehouse. Colour your world

Social scientists have found that the fastest way to feel happiness is to practice gratitude.

When a guy says "I have no idea what you're talking about" it means "I'm thinking of exactly what you're saying I did while I lie to you."

Somebody has said, that a king may make a nobleman but he cannot make a gentleman.

You have to know, when there is a fire in the kitchen, when to flood that fire.

Don't everlastingly read messages into paintings - there's the Daisy - you don't rave over or read messages into it - you just look at that bully little flower - isn't that enough?

I'm saying that there's absolutely no conclusive evidence that Jesus ever really existed, even as a mortal. I don't believe he was a historical figure at all.

Truth is not arrived at by majority vote.

I should thank Mussolini for having declared me to be of an inferior race. This led me to the joy of working, not any more unfortunately, in university institutes but in a bedroom.

I like photography because it is a reality medium, unlike drawing which is unreal. I like to mess with reality...to bend reality. Some of my works beg the question of is it real or not?
