The joy I get from winning a major championship doesn't even compare to the feeling I get when a kid writes a letter saying: 'Thank you so much. You have changed my life.'

A golfer should never make a mental mistake because the ball is just sitting there waiting for you to hit it.

I've been in some seriously bad places playing golf and it's just part of the game. You're going to hit bad shots, you're going to be in bad spots, and each course, when you learn it, you learn where not to go.

I get to play golf for a living. What more can you ask for - getting paid for doing what you love.

One of the things that my parents have taught me is never listen to other people's expectations. You should live your own life and live up to your own expectations, and those are the only things I really care about it.

I chase a little white ball around and work on my farmer tan, that's about it. I think that I've been lucky enough to represent some great companies, and I think maybe that's what it is.

My dad was a big believer of having a golf club that fit me. Always have a golf club that fits you, so you don't have to make any swing compensations for that particular golf club.
