Honestly, I don't read the press. I don't know what they're saying.

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 really hope that I can be helpful in that journey because I do believe that women deserve the same pay. We work just as hard as men do. I've been working, playing tennis, since I was three years old. And to be paid less just because of my sex - it doesn't seem fair.

If you smile things will work out.

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.

We're sisters, we're roommates, we're all that.

I was talking to my mom one time, like, "Gosh, I'm 30." And she's like, "In your thirties you're even stronger than in your twenties." I didn't believe her, but I have played better in my thirties.
