I spent my whole life playing sports and training and pushing myself to the limits.

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.

Honestly, I didn't have the patience for biology or history in an academic sense, but I always liked the kind of big questions.

I just don't find marriage a necessary step in a couple's life.

Good tactics can save even the worst strategy. Bad tactics will destroy even the best strategy.

I believe that poets have to be inside their poems somewhere, or the poem won't work.

If there were mistakes, there were mistakes. But a man has to have a line of work, no?

Unlike celibacy, which people choose, asexuality is an intrinsic part of who we are.

The same goes for envy, anger and insults - said the master. - When they are not accepted, they continue to belong to the one who carried them.

Caleb could be so testy for no known reason. At times, it was like dating a woman with irritable bowel syndrome. Or rabies.

Is there discrimination against women? Yes. There's no denying that the old boys' network is alive and well. But there's also discrimination against men.

Of course if you like your kids, if you love them from the moment they begin, you yourself begin all over again, in them, with them, and so there is something more to the world again.
