I certainly don't lose any sleep if I lose a tennis match.

I believe the brain is like a muscle - like any other it can be improved.

I don't make a habit of watching tennis matches, but I try to watch all the major finals. I try to make time for that. So unless I have something going with the kids where I can't, I try to watch, and I enjoy that.

I was between 2 and 3 in the world for two, three years. That's not exactly where I wanted to be.

Many times the players get in there and it's just about as well as they could have done, and other times they get in there and they favorites and they don't win.

You have to focus on the process. You cannot be glued to the results.
