I have learnt to be even more patient.

You've never seen me dance, have you?

I'm proud to be a symbol like the army knife or the mountains.

You can be stubborn and successful or you can give it up a bit and change things around. For me it's important to have a bit of both.

I've done so many interviews over the years in so many different languages. Radios. Papers. Magazines. There's always another interview to do. It's quite something, I have to say.

The week before the (US Open) I gave a few interviews for CNN, USA Network, New York Times, USA Today and Sports Illustrated which had been arranged beforehand. The reason for giving these interviews is not only because working with the media is just part of the job, it is much more my desire to contribute to the promotion of tennis in the U.S.

When you do something best in life, you don't really want to give that up - and for me it's tennis.
