I am not a robot. I have a heart and I bleed.

When you travel so much, the best and most relaxing thing is to just sit on the couch and not move.

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 definitely have found a balance. I've had so many offers in the past to do different movies or different things and I always choose tournaments over it.

Venus told me the other day that champions don't get nervous in tight situations. That really helped me a lot. I decided I shouldn't get nervous and just do the best I can.
