I think business is the same as tennis. You have to have the love, that helps, or else it's just too much pressure to be able to keep up with.

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.

I feel so sorry that many Christians live in bondage even though Jesus has signed their release form with His own blood.

The mind will enchain yourself, others or both. Your heart will set you / them free

The biggest mistake people make is to try to lose too much weight too fast.

But honest instinct comes a volunteer; Sure never to o'er-shoot, but just to hit, While still too wide or short in human wit.

We have the right of revolution. Revolution does not always have to be weapons and warfare; it's also about revolutionary ideas.

I have no talent for certainty.

Lies save trouble now, but may return in thunder and lightning.

Humility is the foundation by which love manifests.

The nearer you take anything to the light, the darker its spots will appear; and the nearer you live to God, the more you will see your own utter vileness.

Most of the groups I worked with 30 years ago are either dead or dead broke. And it's a shame.
