Anything is possible. You can be told that you have a 90-percent chance or a 50-percent chance or a 1-percent chance, but you have to believe, and you have to fight.

It's tougher for me. But I don't think that's imperative to me starting a new movement, or revive an old movement, to help people.

It's nice to win. I'll never win again. I may have to take up golf - take on Tiger.
