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

Sure, I've been on the Tube...I caught it to Eastbourne once.

I try not to be protected. Because I feel like you can become a little bit of a robot. That's not who I am. And I don't want to be monotone. It's important to be yourself, whatever the cost.

Am I the greatest? I don't know. I'm the greatest that I can be.

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.

If anything, we haven't changed much since we [with Venuse Williams] were kids. We really are the same people.

People see me on the court only as a superhero, grunting and winning. They think you're a robot, and I'm not.
