Definitely sport matures you, if you let it. It definitely makes you grow up because you have to work so hard that if you can't, then you probably aren't going to have the mental capacity to handle it all. That probably played a role in growing up a little faster than maybe other people.

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.

We don't talk about tennis. I figure she knows what she's doing. I mean, what am I going to tell her?

There have been many frustrating games. I don't there's going to be another one that isn't frustrating. That happens, but that's sport. Otherwise why would there be so much glory in victory.

I'm only seeing tennis balls these days. And maybe the occasional fashion sketch.

Every Olympics is something special. If you're fortunate enough to play for your country - there's just so much energy. It's truly amazing.

I truly believe that whoever feels the most confident is usually the one to win.
