Of course, money matters to everyone even if some don't want to admit it. If I won the Race to Dubai, I look at that prize money and think it could pay off my new house or the range I'm building. I am privileged to play golf for a living - look around St Andrews, that's my office.

I don't really remember, but from about the age of five I told anyone who would listen that I was going to be the best golfer in the world.

I've always said the players don't build up rivalries themselves, people from the outside build up the rivalries. I just want to play good golf. I want to try and keep winning golf tournaments.

Going to the gym is great for your body, but it's also great for your mind.

As long as I keep enjoying my golf, then hopefully I'll be able to play well.

I receive huge support from Irish and British sports fans alike and it is greatly appreciated. Likewise I feel I have a great affinity with the American sports fans. I play most of my golf in the U.S. nowadays and I am incredibly proud to have won the U.S. Open and U.S. PGA Championship in the last two years.

As an international sportsman, I am very lucky to be supported by people all over the world, many of who treat me as one of their own, no matter what their nationality, or indeed mine. This is the way sport should be.
