It's such a psychological and mental game, golf, that the smallest wrong thing at the wrong time can distract you from what you're trying to achieve.

I never take myself too seriously.

I'm a golfer - not an athlete.

In my case what happened next in 1999 was that I fell apart over that back nine. When I saw I was in genuine contention that year I felt like throwing up. That remains probably the most nervous I've ever been on a golf course.

People mature at different stages and I feel I'm learning a lot.
