I've developed a karaoke habit. I've become a crooner.

If you can keep playing tennis when somebody is shooting a gun down the street, that's concentration.

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.

I don't go thinking I'm going to lose. I never go into a tournament thinking that. I'll do the best that I can.

I love going to movies.

I do want to look good still; I do want to be healthy.

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.
