What I think I've been able to do well over the years is play with pain, play with problems, play in all sorts of conditions.

I think it's very hard for coaches to work with me. They'll no doubt have a good CV afterwards, but at the same time they're under a lot of pressure.

When I think of the Olympics I only think of good things. I think of what a great event it is and what it has done for me and my career, and changed my personal life, too.

The serve, I think, is the most difficult, you know, in terms of coordination, because you got the two arms going, and you got to toss it up at the right time so.

The nicer the point, the more -- the better I feel, the more excited I get. But I never play that my opponent looks stupid. I think that is wrong. I have too much respect for every opponent I play.

I'm at the top of my game so, when I win or lose, I don't freak out...I don't think we can call it a rivalry yet. There's just to many great players around.

One of my big, big strengths I think early on in my career was that I could learn very quickly. You wouldn't have to tell me the things 10 times or 50 times until I would understand them. You would only have to tell me two or three times.

A man who wins, is a man who thinks he can.
