You can't underestimate anyone.

I love hitting aces. It's not easy, but it makes your life a lot easier.

There are people who live, breathe and dress tennis.

What's going to make me happy is going on the court and holding up trophies, singles and doubles.

I can't become satisfied, because if I get satisfied, I'll be like, "Oh, I've won Wimbledon, I've won the U.S. Open. Now can I relax." But now people are really going to be fighting to beat me.

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.

There's one thing I'm really good at, and that's hitting the ball over a net, in a box. I'm excellent.
