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

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

I just travel all the time.

I am not playing Wimbledon because I am allergic to grass.

I got bad calls every match, and I never got an apology. So I thought it was rather strange.

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

I enjoy life. I always enjoy jokes.
