It's been 18 months since I won on the European Tour and to win the flagship event, I could not have asked for any more.

I started to really believe in myself, and my abilities, when I won the World Under-10 championship in Doral, Florida. I was nine and saw for the first time that I was amongst the best players in the world for my age. This was a massive confidence-builder for me.

I’m three legs toward completing the career Grand Slam at 25. So, I’m feeling pretty good right now.

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.

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.

You know I need that cockiness, the self-belief, arrogance, swagger, whatever you want to call it, I need that on the golf course to bring the best out of myself. So you know once I leave the golf course, you know that all gets left there.
