Sag Harbor' brought me a new readership - it's a coming of age tale about growing up in the '80s.

Even growing up the way I did, I was shocked by the level of poverty I saw as a college student. I thought the best way to understand it was to get close to it on the ground level.

I don't think we can fix poverty without fixing housing, and I don't think we can address housing without understanding landlords.

I teach at Harvard, and focusing on understanding this problem on a national level is a big priority of mine right now - where evictions are going up and down, what cities are actually instituting policies that work, what housing insecurity is doing to our cities, neighbourhoods, our kids.

I don't like most Christmas movies. They're pretty bad, though they seem to make tons of money anyway. Like this movie 'Elf,' I got the script for that, and I turned it down right away. Against my wife's better judgment.

Before the CFPB, there was no single agency or entity within the federal government tasked with protecting Americans from predatory or negligent practices of banks, credit card companies, mortgage lenders, payday lenders, credit rating agencies and other financial service businesses.

You have to go to where you can make money, and you see in the service area, in the technological area, those are the areas where we're going to create jobs.

I'm a pretty disciplined investor and pretty disciplined buyer. I do my due diligence. I do my homework. I don't waste money.
