The US player Andy Roddick reaches speeds of 220 kilometers per hour when he serves. If I train with him every day, I will later be at an advantage against a player whose service crosses the net at 190 kilometers per hour.

My serve can get better, for sure. It's not just about serving bombs, but positioning, variation in speed, in spin.

Seriously, I am not a person that I think much about what happened or what didn't happen or what could happen. I happy about the things that happened to me. I'm a lucky person, for sure, for all the things that happened to me during my life.

Since I was a kid, I've wanted to do sports for a living. In the beginning, I played a lot of soccer, but in the end I chose tennis. I love sports in general ... But tennis is my passion.

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.

It should not be a child's only goal to become the best player in the world. That would be a bad, a harmful attitude.

I always wanted to be honest with myself and to those who have had faith in me.
