I never got to the point of needing drugs or thinking about giving up myself.

I always say golf's a really good exposer of a player's personality.

Americans believe if you go to college, you have something to fall back on, which makes sense. I don't have any degrees. If I hadn't become a golfer, I have no idea what I would be doing with my life.

I can certainly see how people are overcome by depression.

I didn't really get into golf until I was about 14. My mom and dad were taking lessons from a pro an hour and a half from our farm in Cohuna, Australia. When they got home, I'd ask my mom to explain everything they learned - drills and all.

I had to do something special coming in. I didn't do it, so I had to do it in the playoff. Winning the Mercedes is awesome. Winning three times is a dream come true.

In America, if you want to make it as a golfer, you go to college on a scholarship. In Australia, you go to the airport with a plane ticket. The competition just isn't there.
