Don’t let a first-set victory lead into a second-set slump
Ninety percent of my game is mental. It's my concentration that has gotten me this far.
I still have this image: I can't be controversial, I can't say things.
You're always striving to play that perfect match.
If you can react the same way to winning and losing, that's a big accomplishment. That quality is important because it stays with you the rest of your life, and there's going to be a life after tennis that's a lot longer than your tennis life.
I'm not an overly ambitious person; I don't feel like I have to excel.
