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.

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

I'm 37, I'm pretty fit and feel I have another eight years left - which means there's 32 Majors still to go at.

I'm working my way steadily back and I'm feeling good.

People always say golfers don't smile. But there is so much psychology in golf so we have to be a bit robotic.
