In the '70s and '80s, the mentality of America was that everything was disposable. The notion of quality wasn't important.

I was single for most of my life. The best thing that happened to me is my wife. I've got four kids. All of them go to Harvard. Much better than their dad. They're really bright kids.

If you keep your nose to the grindstone, you don't have any nose.

Humans are pack animals. In Biblical times, the great market cities in Europe or the United States, people want to be with other people. And in a way, the more that we're isolated, whether we're living on farms and we're only talking to our cell phone, the greater the need we have for group experience. So while people are saying that no one is going to go shopping because it's just inconvenient, and it's not as easy as buying online, why are people going to concerts? Why are people going to museums? Why are they going to sporting events?

My mom was terrific. I described my mom once. If fear was a color, she was color blind. Nothing frightened her. If I told her that I was going to take over General Motors, she'd say, "You can do it." Just the most preposterous things, ambitious things, she said, "You can do it."

The foundation of leadership is your own moral compass. I think the best quality leaders really know where their moral compass is. They get it out when they are making decisions. It's their guide. But not only do you have to have a moral compass and take it out of your pocket, it has to have a true north.

Everybody has to solve that "meaning of life" and purpose question for themselves. Everybody does it their own way. I think you have to be thoughtful about the way that you're doing it. So I describe it as purpose. If you can think about leading a purposeful life - not just an accumulation but you actually make the world a better place - then I think in the grand scheme of the universe, that that explains our existence. If not, we're just passing through. We're grains of sand and we're blowing in the breeze.
