The thing about tennis is if you stay off for two weeks, or just for three days, you can lose your rhythm quickly. So it's just a question of constant diligence and vigilance.

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.

Be strong, be strong.

There's no heaven on earth. God would have to guide her through the problems.

I think that the proclamation of the Gospel is sometimes nearer to an atheistic point of view than to traditional religious attitudes.

Faith has to take in all the other possibilities it can.

The perceiver of the dream, the one whom the dream is unfolding before, is what we call the Self.

Many people, including Buddhist monks, spend thousands of hours sitting in what they call meditation. In reality, what they're doing is thinking and ruminating upon their problems.

When good friends praise a gifted person he often appears to be delighted with them out of politeness and goodwill, but in reality he feels indifferent.
