My serve and my forehand I pretty much always had, but my backhand was a made backhand. I worked on it for years.

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

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

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.

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.

Once you win, you have no doubt that you can win. So you have gone through it once, and you can do it again.
