I've always wanted to write, but coming from a small-town background - I was born and brought up in Ludhiana - you think you're not the kind of literary person who will write books that will sell. There was always a kind of defensiveness in me.

My understanding is that a book becomes a best seller only when it is pirated, sold on footpaths and at traffic lights.

I look at every book as a new learning opportunity.

While a lot of management development books try to teach you a lesson or give you a scenario of what corporate culture and work practices are about, they're theoretical and written in a sermonizing way. Most people don't get past the first chapter, and they just look nice on the bookshelf.

I terribly miss - we all miss, I think - somebody like the great producer Irving Thalberg. He had a foot in both camps: He understood us creative people. And he understood the money people.

Just take yourself back to September 2001. As that month went on, and as that autumn unrolled, everybody wanted to do something. How can I help? Do you want my blood? Do you want money for the victims? I was a captain in the Marine Corps. I knew what I could do. I was right there. I was ready. I saw it. I moved the rubble with my own hands.

Today, even small entities that trade complex instruments or are granted sufficient leverage can threaten the global financial system.

I felt that one of the things God impressed on me was that I needed to start a nonprofit corporation, so that any money that came my way, whether it was an honorarium, a book sale or a gift, would go into a nonprofit ministry.
