To have the opportunity to complete the slam at the Open at St Andrews, the home of golf, is something I will never ever forget.

My failures have made me look at myself in a way I've never wanted to before.

I'm addicted. I'm addicted to golf.

I've had the luxury of playing golf around the world, and I've spent a lot of time evaluating how to play all kinds of courses.

I don't believe that human beings can achieve ultimate enlightenment, because humans have flaws.

Your private life, exposed, has a lingering effect on your mind and your game.

I do not look back at what might have been. If I did that, playing golf would drive me crazy.
