I had an instinct before and maybe now I don't have that instinct as much as knowing what to do, what shots to hit, where to place the ball, things like that.

Let me say that the path I did take for a brief period of my life was not of reckless drug use, hurting others, but it was a path of quiet rebellion, of a little experimentation of a darker side of my confusion in a confusing world, lost in the midst of finding my identity.

I'm happy with what I've done but it's a challenge to try to win more.

To win Grand Slams you have to be in the right frame of mind, the right physical shape.

Tennis is what I do and is part of who I am.

She [Serena Williams] played some great shots, but so did I, and that was the only difference.

But, you know, I just want to play well and have fun playing well.
