Honestly, I could get in a car accident today and never play tennis again, and then I wouldn't have anything to fall back on. But fortunately enough, I do.

Luck has nothing to do with it, because I have spent many, many hours, countless hours, on the court working for my one moment in time, not knowing when it would come.

I'm an athlete and I'm black, and a lot of black athletes go broke. I do not want to become a statistic, so maybe I overcompensate. But I'm paranoid. Oprah told me a long time ago, 'You sign every check. Never let anyone sign any checks.'

I always say that when I'm playing well, no one can beat me. I'm not just saying that to sound full of myself or anything, but it's true.

All I want is to have fun in what I'm doing every day. I don't want to break records. To become the greatest player ever could take me like...10 more years and I don't think I'll still be playing at 31.

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

I decided I can't pay a person to rewind time, so I may as well get over it.
