Donald Trump has been a good friend for a long time. I texted him after the election and I said 'congratulations, Mr. President. The Nicklauses are all happy for the Trumps,' and I said, 'It's time to bring American together, make American great again as you wish.'

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.

I love the golf courses because it brought the best out of me. It made me prepare, made me work at it, made me do the things I needed to do to be better, and that's what I loved about USGA events. If you couldn't handle it, then you got beat, and that's OK.

Professional golf is the only sport where, if you win 20% of the time, you're the best.

As long as I'm prepared, I always expect to win.

[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.

I think I fail a bit less than everyone else.
