I've probably put up with more criticism than a lot of people out there. At the end of the day, you block out everything, especially with your personal life.

When I was a kid in Adelaide, I dreamed of becoming No. 1 in the world, winning a grand slam and the Davis Cup for Australia.

Why'd you leave the match, huh?

Everyone has to call 'time' at some stage.

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.

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.

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.
