I'd been told there are 10 difficult holes and eight impossible ones. I'm still trying to work out which the 10 difficult holes are.

Golf is difficult to get your personality over because you are such a bottle of concentration.

People confuse being world No. 1 with winning a Major championship.

I never take myself too seriously.

Listen, everything I did in my childhood was competitive. Everything we did my dad made it into a game to win. We used to drive my mum nuts.

The satisfaction you get when you finally beat your dad is amazing, that rush of adrenaline.

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.
