I never close my mind to anything and eventually want to branch out. But for now, tennis is still number one for me.

Family's first, and that's what matters most. We realize that our love goes deeper than the tennis game.

If you can keep playing tennis when somebody is shooting a gun down the street, that's concentration.

I'm a high-performance athlete: I'm running, I'm sprinting, I'm sliding, I'm doing pretty much everything and the last thing I want to worry about is my chest. I want to just worry about playing the sport at the highest level that I can.

You can't underestimate anyone.

I have started to realize that I am really just a world athlete and a world entertainer -- I am a world-known person, I am a global icon.

I wish I could play like Roger Federer.
