My dad said: 'It looks like you'll be world No.1 in a few hours and I wanted to be the first to say congratulations.

You're the only one in control over your golf ball. It's not like tennis: you're hitting a shot and somebody's hitting it back at you.

I'm heavier, but with muscle rather than flab. It's a massive difference. It means I don't get as tired sometimes and it means that I'm hitting the ball a lot farther, about 15 yards more with my driver.

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

You don't win tournaments by playing well and thinking poorly.

Golf is played between the ears and if you are not 100 percent focused on what you are trying to do, then people will go past you no matter who you are.

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.
