Sometimes the biggest problem is in your head. You've got to believe you can play a shot instead of wondering where your next bad shot is coming from.

Well, I think that Augusta is not the same golf course that I grew up on. Bobby Jones' philosophy was giving you space off the tee; if you put it in the right side of the fairway, you ended up getting the right angle to the green.

I learned early in my career, where you get so wrapped up and so excited, that all of a sudden you don't think. So I worked very hard to keep myself suppressed. And that's one of the reasons I wasn't gregarious with the gallery.

The biggest rival I had in my career was me. I couldn't control Arnold Palmer, Gary Player, Tom Watson or Lee Trevino. The only person I could control was me.

The size of your accomplishments, the quality of your achievement, will depend very largely on how big a man you see in yourself, what sort of image you get of your possible self, yourself at your best.

I think my biggest achievement was being part of a team of outstanding, entrepreneurial military leaders and civilians who helped change the way in which America fights by transforming a global special operations task force - Task Force 714 - that I commanded.

No matter what your company does - build, manage, produce, import - as an owner, you can't avoid the hard work and skip straight to success. No class can give you that, no YouTube video can teach it, and no book can mark it off your list.

I'm surprised by the success of anything I do, but it's gratifying when the public approves.
