The toughest are people mistakes, when you put the wrong person in a job. Sometimes you're too slow to move them out. Or not getting the right people involved to solve a problem, or doing something out of anger; you learn, just don't do that. But I'd have to say the Whale was one of them, and I would also have to put Bear Stearns and Washington Mutual on the list at this point.

Finance went from being a small business, effectively, to being a big business. In part, that's the growth of the world's wealth. That's called savings.

India is a huge democracy. Prime Minister [Narendra] Modi has ambitions to try to fix the infrastructure, the rules, taxes, education, and to lift up the Indian people. And we're hopeful that that's going to create positive momentum.

I always tell people, "There's a book on everyone." I get some of that book before I do anything. If I want to deeply understand someone's reputation, I'll talk to their friends, their former bosses, their peers, and I'll learn a lot about them. I want them to be trusted. I want them to be respected. I want them to give a s - -. Then there are the intangibles: physical and emotional stamina, the ability to confront issues. I can ask all I want about those things, but I also have to see a lot of it.

I hate the word universal, because I don't know exactly what it means. The question is, does it work for the client? Travelers was a diversified, financial conglomerate that did very well. The businesses had nothing to do with each other.

When people talk about people being left behind - middle wages have not gone up for years, and we should recognize that, and there I think we need growth and skills - but there are these other people who have been left behind. When I say out loud, "Fifty percent of inner-city schoolkids do not graduate from high school," that is a national catastrophe. We should be ringing the alarm bells. It's not fair.

From my point of view, the American financial system - including banks and investment banks - is far safer because of capital and liquidity requirements. Despite all the turbulence so far this year, I don't think anyone's questioning our system. And that, obviously, is a good thing.
