With all the injury problems we have in men's tennis at the moment, I'm happy to still be standing.

The serve, I think, is the most difficult, you know, in terms of coordination, because you got the two arms going, and you got to toss it up at the right time so.

Obviously, matches and all that stuff takes its toll on your body and so forth. But as you get sort of a bit older, a bit wiser, and a bit more experienced, you know also how to handle it.

You live during the match, and you have strong emotions, but you don't want to get too overexcited. My body's totally flat now. I cannot move anymore. I'm totally exhausted, just because of the tension out there.

I did all the right things in so many tournaments. But like I said, sometimes in sports it just goes the other way. Maybe you've already won so much that it evens it out a bit sometimes. I don't know.

Confidence? Are you kidding me? I mean, please. Look, some players grow up and play like that. I remember losing junior matches. Just being down 5-2 in the third, and they all just start slapping shots.

I love tennis! I've always felt like this because it is such a classy sport with a great, competitive flair to it.
