What I'm trying to do is to create excitement. So people looking at the Bloomberg's office building say, "My goodness, what's going on here? There's something different about this company." You want the employees to get psyched. And it's a chance to meet each other. My job is to get people to work together. With free food and no offices, even for Bloomberg, this might be considered one of the world's great corporate headquarters.

Nobody wants a job where they don't have authority to go along with the responsibility. Quite the contrary. The more authority you give people, the better people you can attract, and the harder they're going to work, and the more loyal they are going to be.

I've got the greatest job in the world. There's no other job in government where cause and effect is so tightly coupled where you can make a difference every day in so many different ways and in so many different people's lives. It's a great challenge.

I'm worried about the world because there's chaos in the Middle East, and I think the Iranian deal [to lift sanctions] is going to continue the Shia-Sunni battles, the Persian-Arab battles.

New York has been, and will continue to be, a magnet for people from all over the world. This is where the arts, business, research and technology converge to create the world's foremost urban economy.

The governor of Texas was a real climate change, well, "skeptic" would be a nice way of phrasing it. Still, though, Texas is a leader in renewables. So, what I care about is what politicians are actually doing, not what they are saying.

The next day after I got fired, literally the next day, I started a new company.
