I'd much rather win in three or four sets than go the distance all the time; I seem to put everyone through the wringer quite a bit.

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

Maybe I have to work a bit harder on clay. It's a challenge and I've always liked challenges. Whether I will ever win the French and master playing on clay, who knows? But I'll give it a shot.

That's when you've got to grit your teeth and hang in there and try and find a way to win when you're not playing your best tennis - that's what I can be proud of
