It's thrilling and it's an honor to be part of something bigger than your own self.

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.

You will get what you wish for.

Perception precedes reality.

I don't worry about things that aren't important.

The thing that I prefer, when I'm working on a book, is to do a seven-day week, because it's easy to lose some of the details of what you're doing along the way.

Writing well is the best revenge.

Liverpool players must play like a lion, give his all. There must be determination, commitment and resolve to be a Liverpool player.

Your thoughts and emotions are yours alone.

Where you place your focus, there will be your Heart and that will be the Spiritual Heart.

Our first computers were born not out of greed or ego, but in the revolutionary spirit of helping common people rise above the most powerful institutions.

It does not matter whether you win or lose, what matters is whether I win or lose!
