Forget about tennis, I was scared to open my mouth. I didnt even feel worthy of saying something and not sounding stupid.

I do still have some of the experience from playing, but it's been so long since I've been out in those quarters, semis, finals, the important final matches, just against the top players.

Yes, I made mistakes by rebelling, by acting out in confused ways.

Now a lot has changed and I can separate a lot of things.

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

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

I just want to get to the level where I can say that that's my level, just try to play well, get up there.
