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.

Growing up, I knew you were supposed to have a profession - and something better than being a shopkeeper, which is what my parents were.

If your life lease, your existence was canceled tomorrow, what would you wish you had done? What are the things you would like to impact? Start on those and you can change the world. Maybe you can only make your neighborhood a little bit better, or make someone's life a little bit better. Isn't that the kind of purpose?

I think success is about purpose. People ask about success at different points in your life. As I look back, I think people that are successful feel good about what they are doing, and they can look back at what they've done and they feel good about it. People sometimes ask about success and they say, "What's your legacy?" and I say, "I think it's really a dumb question." I think the question is: What am I doing now? Do I feel good about myself? Am I proud of myself? Whatever purpose there is in life, I think success is about purpose. It's not about material things.

You have to keep being curious. The notion that the present is different than the past, and the future will be different than the present, and the present is past, as we say it. I think I, by nature, am an optimist. Maybe I was driven to escape from my childhood and to be something, create my own world or career the way I wanted it to be. And I keep doing that in very interesting ways.

I think different societies, cultures, individuals, teams of people, make the world a better place. The founding fathers, they made New England, they made those 13 colonies. I don't know if they thought they were changing the world or just changing their world, but they did make the world a better place. Doctors that cure patients or cure diseases or make discoveries, they're making the world a better place. Can I make the world a better place by selling underpants? Not really. That's just the means. That gives me resources to try to make the world a better place.

My Picassos and Ferraris - those are kind of just toys. Those aren't the things that matter. What matters in the car collecting or the art collecting is to learn about it, and then actually not the acquisition but to put them into a collection that I think is curated. You know, so something of me in the collection that the artist actually created the work. If I was going to collect art, it had to be something of me, my eye, things that appeal to me so when I looked at it, it would really look like a collection, not just an accumulation of stuff.
