I'm afraid there are no replays or second chances in amateur or professional golf, and that's the way it should be.

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.

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'm sure there was an educational angle to the trips (I think one was to the Ulster Museum) but it was the fun and banter I had with my friends I remember the most.

Because I lived so close to the school and walked there every day, I used to enjoy the school bus trips.

In a serious sense, wanting to change something from the past doesn't work for me - change something you don't enjoy now rather than regretting it later.

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.
