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.

Even when I was No. 1 in the world, I was taking it one match at a time. I never was a player to look too far ahead, the way draws can pan out.

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'm an outside chance at Roland Garros but my focus is really on Wimbledon where it is realistically between me and Roger Federer to win.

Grand Slams are different. If you can get through a few matches, the draw opens up and you get confident. You just need a little bit of luck early, you get through those opening matches and you never know what could happen.

(Andy Roddick's) a different kind of guy. I don't spend a lot of time with him. His coach in the past (Tarik Benhabiles), I didn't have a lot of time for at all. He was a bigger problem than Andy.

I wanted to work towards the four majors and the Davis Cup. I know to a lot of people it may not mean too much, but to me (Davis Cup) means an awful lot.
