What do I mean by concentration? I mean focusing totally on the business at hand and commanding your body to do exactly what you want it to do.

As long as I can stay competitive and have fun doing what I'm doing, I guess I'll keep doing it.

If you can concentrate on what you're doing and have the desire to do the things you have to do to win, you'll succeed.

I started [flying] by being scared. When I was an amateur I played a couple tournaments and I had to fly, and got into weather and stuff, and it scared me, and I decided that would not work, I had to learn to fly, I had to find out about airplanes and aeronautical engineering and what it was all about.

I think, first of all, I'm very proud of Sam Saunders in general. I am happy to see him playing well and his performance has been good. He is coming on as I hoped he would at this stage of his life.He is a fine young man as well as a fine golfer. He is doing things the right way.

I had a system, and the system worked.

Phil [Mickelson] has done a great job. He's a great player and he's conducted himself very well through the years. He's been a good ambassador for the game. He hasn't won in a while, but he still has time, and it wouldn't surprise me if he won again.
