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.

People see me on the court only as a superhero, grunting and winning. They think you're a robot, and I'm not.

I always believe I can beat the best, achieve the best. I always see myself in the top position.

Nothing comes to a sleeper but a dream.

I wanted to get really fit. I wanted to lose some weight. So I've been doing Pilates and yoga, trying to lean out my body so I won't be bulky.

I am basically a blazer. If I were a clothing item, I would be a legging and a blazer.

I'm not one to blame anyone else for anything. And I don't think anyone else should either.
