I do notice that I am tired.
I was shy when I was a kid, I was very shy, but now I think I've improved a lot. I can speak OK with the media and with the people. My English is still bad but I feel a little bit better now than before.
I only ever run when there's some point to it - say, if it's in a game of tennis.
I play each point like my life depends on it.
I learned during all my career to enjoy suffering.
Confidence is the most important thing in this sport, and the confidence from winning Wimbledon would make it easier to win the Olympics, too. Either would be very difficult, both even more-but the player who wins Wimbledon will be the favorite for the Olympics. It can happen.
