I was lucky enough to win the Davis Cup in my first year in 1999. I won my first slam at the U.S. Open in 2001 and became world No. 1 later that year. By the age of 20, I'd done it all.
I'm more in that Rafa Nadal high-energy high-octane mold out there. I wear that emotion on the court. That's how I play my best tennis. People either like that or not. And I can't change that: that's who I am on a tennis court.
There are people who love you and people who hate you, but for me, more so, people only think they know me by how I act or perform on a tennis court.
I don't have too much spare time, but I try to play games as much as possible. I played a little growing up, but I never played any tennis games before.
I'm not to eager to play tennis in my spare time. I'm more interested in doing gym work and stuff like that. We have a lot of schools and courts around where I live, so if I really want to play, I don't need to go too far.
I'm fortunate: I can play as long as I want to play. There's no coach or trainer who is going to say to me that I'm dropped or sacked, it's time to move on. I can play as long as I want to play.
