Unfortunately the world is what it is now. People don't get along for whatever reason. As professional athletes, in a way we're almost ambassadors for peace, because sports brings everyone together.

Tennis is a huge part of my life, but I don't base my self-value or my self-worth or the quality of my life on my results on the court.

I think I've been fortunate to be at the top of the game and in the media for years, and a lot of times, people want to be your friend when you're on the top. You know, there have been times when I've been injured and I never got a phone call. So that's the way it is.

Serena and I, we don't have anything to prove ... we still set a very high standard.

Winning once is never anyone's dream. We all want to keep winning no matter what it is, or if we retire, we all still are striving toward something, probably most of us are.

I'm this overachiever type, I'll just work and work and I'll just do it over and over and over again.

The naysayers, they don't mean a thing.
