[My boys] they're all different. Jackie was very competitive. He was a tough kid - a little bit like Nick. Steve was sort of a finesse guy. He was a little bit like Nick - if he could touch it, he'd catch it. He played wide receiver at Florida State. Then, Gary came along and Gary was more my size.

The most difficult thing for me is keeping yourself focused on what you're doing. As you go play, you try to get your focus and desire. You don't do it to the level you would do it if you wanted to win. You have to work at it and be on top of your game.

It's hard not to play golf that's up to Jack Nicklaus standards when you are Jack Nicklaus.

My ability to concentrate and work toward that goal has been my greatest asset.

Nobody - but nobody - has ever become really proficient at golf without practice, without doing a lot of thinking and then hitting a lot of shots. It isn't so much a lack of talent; it's a lack of being able to repeat good shots consistently that frustrates most players. And the only answer to that is practice.

Confidence is believing in your own ability, knowing what you have to do to win. My confidence was developed through preparation.
