I played pretty well in my twenties, don't get me wrong! But my consistency is better [in my thirties], my momentum is better, my wins are quicker.

I have started to realize that I am really just a world athlete and a world entertainer -- I am a world-known person, I am a global icon.

I don't go there thinking I'm going to lose. I never go into a tournament thinking that. I'll do the best that I can. I need to be at my peak and my best is holding up the trophy. Anything less I wouldn't be really excited about. So that's all I can focus on.

When you lose, you get up, you make it better, you TRY AGAIN.

The knee just isn't 100 percent. It's hard to be out there when you know that you can't play at your best and could potentially make it worse.

I've never felt invincible. I've never used that word to describe me ever.

My coach has said to me, "When you win a match or a tournament, you don't even think about it - the very next minute you're like".
