My motto has always been that you can't say, 'Oh, it won't happen to me.' You have to say, 'That can happen to me.' So always be aware that things can happen.

If I go down, it's never easy. At least my opponent knows they have to go to the end of the earth to take me out no matter what the circumstances. I do try to compete. Even if it's not your best day, I just try to walk off the court knowing I gave 100,000 percent.

The most fun part about working out is being done - getting through the workout, let's be honest. But that feeling afterward? Yeah, that's worth it.

'Oh and Oh' is a tennis term... It's a nice way of saying you took your opponent to pieces.

As long as we're fit, we just have so much to give on the court.

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.
