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 have seriously thought about retiring, but that was on a good day. On a bad day I've thought about killing myself.

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

In tennis you move a lot. Golf you dont. In tennis, you can have a bad half-hour, but you cant in golf. You can lose the first set in tennis and still win.

It's very nice to see when somebody who wanted to work hard and is willing to put the work in gets rewarded for it.

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