Someone like Billie Jean King is completely my idol.

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.

You have to believe in yourself when no one else does.

If I'm winning, I have to act like I'm not bored. If it's A tough match, I have to act like I'm having A good time. I'm a drama queen.

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 like to lose-at anything... Yet I've grown most not from victories, but setbacks. If winning is God's reward, then losing is how he teaches us.

The guy is the greatest male athletes of all time.
