Still, accomplishment is unreliable. "Succeeding," whatever that might mean to you, is hard, and the need to do so constantly renews itself (success is like a mountain that keeps growing ahead of you as you hike it), and there's the very real danger that "succeeding" will take up your whole life, while the big questions go untended.

I don't believe in luck, I believe in preparation.

I think my greatest victory was every time I walked out there, I gave it everything I had. I left everything out there. That's what I'm most proud of. I can't go win Wimbledon anymore, so if what I've done in the past is not good enough, let it go. Because I'm certainly not sitting around thinking about it.

Always have one possibility in mind and that is to go to the top, to be the best. Everything else should just be a means to that end.

There are other players who were more talented, but there is no one who could out-prepare me.

I didn't know where my career was going to go. Somehow, people sensed that I have certain talents and cast me in these bizarre, off-beat roles, which I have no regret about. I've enjoyed playing every one of them.
