Phil Mickelson

I love competing against the best players. I have a huge challenge, and that's to win a U.S. Open and complete the Grand Slam. I enjoy that challenge. Every year it comes around, I get excited to try to conquer that opportunity. I love it.

I doubt very much that the chief executives of any of the Fortune 500 corporations can name five edible plants, five native grasses, or five migratory birds within walking distance of their homes, or name the soil series upon which their house sits. And I would contend that if you don't know where you are, you are in fact nowhere at all.
