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.

We all know who the real number one is. Quite frankly, I'm the best in the world.

You can't play well if you don't look good.

It's so great to have that opportunity with so many young American players coming up now. It's just so exciting. We have to root for the home country.

Growing up I wasn't the richest, but I had a rich family in spirit. Standing here with 19 championships is something I never thought would happen. I went on a court just with a ball and a racket and with a hope.

Having a pulmonary embolism is definitely easier than heart break.

My mom taught me how to sew when I was super young; I used to make clothes for my dolls. When I finally went to [fashion design] school [in 1999], I really took to pattern making. Everyone in class was good at something; I was the person, if you need help with your patterns, you come to me and I would help you out.
