Tennis is not like other sports where the coach is hired by an independent entity, and that makes a huge difference in the dynamic.

I have seriously thought about retiring, but that was on a good day. On a bad day I've thought about killing myself.

If you become great, then you can become happy. If you're happy first, it's much more difficult to be great.

It's flattering to be compared in any way to Tiger Woods, because he's the best player in the world.

I just travel all the time.

When I lose, it doesn't just go to my head; it goes to my heart too. If you're at all in the match, if you love to play and ein, it must go to your heart.

If you lose, it hurts, but as long as you have fought hard, you can still feel good about yourself.
