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.

Everybody who plays me plays me so hard because they always want to beat me.

I think my father is probably the best coach ever because, if we talk about numbers, he's got a lot and he's only had two players.

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.

Think of all the girls who could become top athletes but quit sports because they're afraid of having too many defined muscles and being made fun of or called unattractive.

I was glad to watch the soccer because it helps my tennis game, realize maybe they're just rooting for the underdog.

I always say if I play my best it's difficult to beat me
