Golf is fluid. It's always changing. It's always evolving. First of all, you never master it.
My kids are doing just great.
My failures have made me look at myself in a way I've never wanted to before.
I mean, as an athlete, as a competitor, you have to have that belief in yourself.
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.'
I wake up every day and I can't wait to go to work, and that's a gift. Not too many people have the opportunity to feel that way.
