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.

Winning a Grand Slam is not something I'll think about.

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.

My dream was always to win a grand slam, and my second dream was to be No. 1.

Project Grand Slam.

I'd like to win the Masters and the PGA and complete the career Grand Slam.
