Ask yourself: What forms the decisions you make? What is it that gnaws at you? What are your crucible moments?

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.

My friends don't understand, whether it's belonging to a country club or playing golf, or whatever a vacation is, that should make you happy. And it's like, "No, happiness is much deeper." I think people have to struggle to find things that give them purpose, the real meaning. Why am I alive? Why did God bless me with these skills or these resources? What am I to do with them? If God just lets some person be very fortunate, let's say financially, it's kind of a funny God.

I am really proud of the development of the people on my team as they grow in purpose; they like what they see in the mirror.

At that time when I was struggling with being successful in a financial way, people would say, "You should be very happy. Look how well you're doing financially," and I was struggling to find purpose, if you would. There's quote from Einstein that said, "Happiness and well-being are the ambitions of a pig." And I thought, "Boy, that's exactly how I feel."

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?

I think finding the way in life is the hardest part. At every stage of life, every trial, every success, you know, you're going into some kind of fog. There isn't a plan that suddenly reveals itself, and you go, "Ta-da! Now I understand."
