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

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

But it's very difficult, I can tell you I played the Czech Open a few times and it's very difficult just to go on to a scene where the course is prepared differently when the greens are fast and he's not used to it and they're hard as a rock and he's not used to it.

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

When I lose, it doesn't just go to my head; it goes to my heart too. If you're at all in the match, if you love to play and ein, it must go to your heart.

Tennis is not like other sports where the coach is hired by an independent entity, and that makes a huge difference in the dynamic.

I'm certainly not sorry that there were some things I missed. You may think you're missing something at that time but later when you look at it, you didn't miss anything.
