Tennis has always been a big challenge to me and to be able to play that kind of tennis - well, only tennis can produce these feelings for me.

You can have a certain arrogance, and I think that's fine, but what you should never lose is the respect for the others.

When you lose a couple of times, it makes you realize how difficult it is to win.

I never look back, I look forward.

As long as I can focus on enjoying what I'm doing, having fun, I know I'll play well.

You can't measure success if you have never failed.

Age, what is it? It's not a figure that has ever meant anything to me.

I have always been guided by striving to show the best that I could. That is what kept me going in tennis and it is the same now.

There is no relief at it being over. There is the joy of winning it.

My big dream was to work as a photographer for 'National Geographic.'

It doesn't hurt to lose my crown, it hurts to lose.

If it has to be done, you have to do it yourself.

You've got an empire to run, I'm just your arm candy.

You realize that you aren’t leaving the battle field behind but are actually taking it with you and it will be a part of you forever

It all starts with a tiny, stupid idea, then one thing leads to another, and suddenly, you find something amazing: yourself.

There’s nothing wrong with fighting when you have no choice. As a matter of fact, it’s what you should do, but when you fight, fight to win.

What exactly is success? For me it is to be found not in applause but in the satisfaction of feeling that one is realizing one's ideal.

The sole life which a man can lose is that which he is living at the moment.

Greatness brings no profit to people. God indeed, when in anger, brings greater ruin to great mens houses.

One of the most important milestones we'll all hit along the way is the moment when we finally own our unique point of view and realize how priceless it is.

If you can't understand the blues, you don't know much
