But the thing I think that thrust me possibly into the public consciousness, I had just been elected Bishop of Lesotho. I had gone there to become bishop and I went for a retreat. I don’t know — I mean, I don’t know what happened but it just seemed like God was saying to me, “You’ve got to write a letter to the Prime Minister.” And the letter wrote itself.

I think it was a combination of feeling and judgment. I happened to be that sort of person that enjoyed making out plans, but I also enjoy changing plans. On an expedition, although I may start out with a detailed plan, I’m prepared to change it at any moment and completely redo it. So our expeditions turned out to be very adaptable ones. We achieved the final objectives just the same as many other expeditions, but maybe we had more fun in the process because it seemed something we could vary. We still carried on to achieve our major objectives.

When I was 17, I read a quote that went something like: “If you live each day as if it was your last, someday you'll most certainly be right.” It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself: “If today were the last day of my life, would I want to do what I am about to do today?” And whenever the answer has been “No” for too many days in a row, I know I need to change something.

We called that the 'story crisis,' and we never expected to have another one. But you know what? There's been one on every film. We don't stop production for five months. We've gotten a little smarter about it. But there always seems to come a moment where it's just not working, and it's so easy to fool yourself - to convince yourself that it is when you know in your heart that it isn't.

The problem is I'm older now, I'm 40 years old, and this stuff doesn't change the world. It really doesn't. That's going to break people's hearts. I'm sorry, it's true. Having children really changes your view on these things. We're born, we live for a brief instant, and we die.

I think the work speaks for itself. I don't think that people have special responsibilities just because they've done something that other people like or don't like. I think the work speaks for itself. I think people could choose to do things if they want to but we're all going to be dead soon, that's my point of view. Somebody once told me, they said "Live each day as if it would be your last and one day you'll certainly be right." I do that. You never know when you're going to go but you are going to go pretty soon. If you're going to leave anything behind its going to be your kids, a few friends and your work. So that's what I tend to worry about.

You know, Dr. Edwin Land was a troublemaker. He dropped out of Harvard and founded Polaroid. Not only was he one of the great inventors of our time but, more important, he saw the intersection of art and science and business and built an organization to reflect that.

Design is a funny word. Some people think design means how it looks. But of course, if you dig deeper, it's really how it works. The design of the Mac wasn't what it looked like, although that was part of it. Primarily, it was how it worked.
