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

I am a proud product of Irish golf and the Golfing Union of Ireland and am hugely honoured to have come from very rich Irish sporting roots I am also a proud Ulsterman who grew up in Northern Ireland. That is my background and always will be.

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 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.

My dad's a scratch golfer and I've got the knack of seeing something and then replicating it. I saw my dad swing a club and I worked out how to do the same thing. My backswing and follow-through have been basically the same since I was two.

How can I intimidate Tiger Woods? I mean, the guy's got 75 or whatever PGA Tour wins, 14 majors. He's been the biggest thing ever in our sport. How could some little 23-year-old from Northern Ireland with a few wins come up and intimidate him.

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.
