A lot of times I had some problems, but I always had the passion and the personal motivation to keep going, to keep working hard, keep fighting for the things that really motivates me. That's all.

My goal is to improve my game, stay healthy and be competitive. If I have that, I know I can be able to win tournaments, which in the end is what it counts.

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.

Two weeks ago, I was in a fantastic situation, winning at Roland Garros. Now, losing in the first round, it's tough. The tour continues. Life continues. This is a sport of victories, not a sport of losses. Nobody remembers the losses. I don't want to remember the loss.

I've stayed calm when I'm winning and I've stayed calm when I've lost. Tennis is a sport where we have a lot of tournaments every week, so you can't celebrate a lot when you have big victories, and you cannot get too down when you're losing, as in a few days you'll be in the next tournament and you'll have to be ready with that.

You know, a lot of things changed. What never changed is the illusion to keep playing tennis, the illusion to keep doing well the things, and the illusion to be in a good position of the ranking and play these kind of matches.

I feel that love. I feel that energy. I always felt that energy when I'm playing in New York.
