Tennis is mostly mental. You win or lose the match before you even go out there.

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.

Intelligence and common sense, what makes a person a real genius.

Pride is the direct appreciation of oneself.

Raindrops keep fallin' on my head. But that doesn't mean my eyes will soon be turning red. Crying's not for me. Cause I ain't gonna stop the rain by complaining.

Take the military option off the table - we have already seen it doesn't work.

A song is what you fall in love with first, but then I think a band's ideals and a band's sense of fashion and a sense of how they treat people is what you fall in love with afterwards.

I never got to the point when I felt like running away from it all.

I left drama school and went straight into a 10-week film for which I was paid £75 I might say, which for 1962 was one heck of a lot of money.

I think, at the end of the day, the real antagonist is the brokenness of humanity.

I don't think people understand how stressful it is to explain what's going on in your head when you don't even understand it yourself.

With goals you can create the future in advance.
