I have lived my whole life with high intensity.

It is important to recognize the small successes.

You just try to play tough and focus point for point. Sounds so boring, but it's the right thing to do out there.

I learned during all my career to enjoy suffering.

I am decidedly unfriendly during a golf game, from the first hole to the last.

My tennis is aggressive, though I wouldn't say that it's more physical than technical. I rely more on technique than physique, but being physical is always a help to me.

You have to accept both losing and winning well. I've stayed calm when I'm winning and I've stayed calm when I've lost.
