Tennis is my job, but it's not my life.

There's one thing I'm really good at, and that's hitting the ball over a net, in a box. I'm excellent.

I feel as a brand I'm here to be around for a long time.

Most people that do play nowadays hit really hard. It was good to get someone that hit really hard early on.

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.

Hopefully, we can build a rivalry and we'll be able to do this a lot. Make a legacy, then retire champions.

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.'
