Just always believe in yourself. "Champions adjust." It's a line I learned from Billie Jean King, and sometimes your dream adjusts. Be willing to adjust with it and see where your opportunities ... sometimes a door closes but a window opens, so just follow your dreams and continue. You never know where it's going to take you.

Id like to imagine that in order to beat me a person would have to play almost perfect tennis.

The thing that's most important in getting you in the best mindest is just being prepared - having a great practice, and knowing that no matter what knowing you're going to go in with confidence. You need to have that confidence to power through.

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.

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.

If I didn't play tennis I don't know where I'd be.

I believe I live in a black and white. I think things are like either black or white. I don't really believe that much in the gray. I think that there's gray for a lot of people, but I don't live in the gray. I realize whatever action I have or take, it's going to have a consequence -- either good or bad. So I live my life in a way where I don't have bad consequences. I just notice there's a lot people around me just live in the gray. I don't know, for me, I'm just really straightforward.
