You get thrown off balance out there. And I never recovered. Well, I haven't recovered yet.

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.

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 was very excited when I first started to travel so much. In fact, I was amazed that people were paying me to travel to play the game I loved.

To be a top-class athlete, you have to train hard, you have to eat right, you have to get enough rest. I feel the way golf is going nowadays, you have to treat yourself as an athlete.

If I'm playing in the morning, I'll get some carbs early: porridge with chopped banana. If I'm playing in the afternoon, I'll start with less carbs and have some eggs and fruit for breakfast, then a light lunch about 90 minutes before I play, so I don't feel sluggish or full.

It may come as a surprise but I also really started to get into history while I was at school. I found the projects about World War Two fascinating - perhaps when I get the time again, I could pick up where I left off.
