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

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

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

What I like about golf is there are no bad calls.

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.

If I don't practice the way I should, then I won't play the way that I know I can.

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