You can talk about strategy all you want, but what really matters is resiliency.

To be successful in anything, a person must always want to be better, not only than your opponent but better than your last performance. Done correctly, being competitive is a wonderful way to always try to be a better person by learning from your mistakes and capitalizing on your successes.

Early in my career, my 3-, 5- and 9-irons performed differently than my other irons. But I adapted and made them work.

The positions I played in football, being a quarterback and a defensive back, you had to kind of have a little independent thinking.

I can forgive the body breaking down. It's a little tougher to forgive that mental lapse.

Golf is the only-est sport. You're completely alone with every conceivable opportunity to defeat yourself. Golf brings out your assets and liabilities as a person. The longer you play, the more certain you are that a man's performance is the outward manifestation of who, in his heart, he really thinks he is.

I don't sleep well. I rehash everything in bed. The mind's still working.
