The movie business was changing, I didn't want to turn 60 in the job. I picked 60 as an age where you are young enough to have a new life but not so young you can wait. And I had this incredible need: I had been so blessed in life and I wanted to give back. So I left Paramount with great joy, I have to say, and with great fondness for the memories I have in the movie business.

We do share with my mother what I would refer to as an anxiety gene. And I think it is genetic, that I worry about everything. Not every day, I don't want to say it like that, but I do worry a lot about - what was the line I heard the other day, when I was saying to a girlfriend of mine that I worry? She says, "Yes, I spent my whole life worrying - and some of the things actually came true."

We have many dreams and many different chapters in life and I think life is about chapters. For me, from the time I was pretty young, I always thought that if I was lucky enough to achieve my dreams and if I had financial security, at a certain point in my life I wanted to give back. I wanted, just corny as it sounds, to try and make the world a better place.

There's a Harvard Business School thing that says, 'Every 10 years you should replant yourself,' and the only way to keep young is to learn new things and keep curious.

My father died at 42, of a heart attack. My mother was 32 then. She never wanted to be a victim. And that really resonated as a nine-year-old child. And one of the most revealing things was, very soon after my father died - he was in real estate and he owned some modest buildings - they came to my mother, the men that worked for him, and they said, "You don't have to worry. We will run the business and we will take care of you." And my mother said, "No, you won't. You will teach me how to run the business and I will take care of it and my children."

When you rule in a culture of fear, you're not getting the best out of people.

The major difference I've found between the highly successful and the least successful is that the highly successful stick to it. They have staying power. Everybody fails. Everybody takes his knocks, but the highly successful keep coming back.
