I really think a champion is defined not by their wins but by how they can recover when they fall

I think a smile can make your whole body. Models, they look fabulous, but they don't smile, and they look so mad.

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

It's so great to have that opportunity with so many young American players coming up now. It's just so exciting. We have to root for the home country.

I want it to be more natural. Right now it feels really forced. Seems like I've never done a curtsy before, which may be true. But I'm looking forward to nailing it.

I don't go there thinking I'm going to lose. I never go into a tournament thinking that. I'll do the best that I can. I need to be at my peak and my best is holding up the trophy. Anything less I wouldn't be really excited about. So that's all I can focus on.

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.
