As far as everyone else's opinion, I mean, if I would have thought that everyone was right, I probably wouldn't have left Compton, so I don't get too caught up on what the next person thinks.

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.

Trust is like a valuable antique, once gone, it can never be replaced.

You can’t control other people’s actions, but you can control who “thinks” they have control over you.

I think I'm going to keep my Irish accent forever now in any movie I make, because chicks dig it and that's all I care about now!

What was invented two thousand years ago was the spirit of Christianity.

All governments lie, but disaster lies in wait for countries whose officials smoke the same hashish they give out.

In them days, it was just still not illegal to kill an Indian. If you killed an Indian, you'd be very unfortunate if you got probation - most of them were released immediately.

I am not an autobiographical writer. I'll take little elements here and there from things that I've actually experienced-counting eyelashes on a sleeping beauty, for example.

One day we will spend our sunset years telling our children and our children's children what it was once like in the United States where men were free.

I go out on stage, and my intention is to make the first four rows bleed from their ears.
