The real magic in National Geographic isn't how much money they have left at the end of the year. It's the fact that through their overall focus they are reaching hundreds of millions of people and educating people about the world. It just happens to be done in a business-oriented kind of way that is more sustainable.

You can be entrepreneurial even if you don’t want to be in business. You can be a social entrepreneur focused on the not-for-profit sector. You can be an agriculture entrepreneur if you want to change how people think about farming. You can be a policy entrepreneur if you want to go into government. The idea of an entrepreneur is really thinking out of the box and taking risks and stepping up to major challenges.

The attackers are the people with bold, innovative ideas who are trying to disrupt the status quo and usher in a better way. The defenders are the incumbents who try to defend what they have. We need to bring an attacker mindset to whatever we choose to do.

I do think that people have an obligation to give back but that doesn't necessarily mean that you give back just the traditional way. Maybe there's new ways to give back and make a contribution.

I think the more you have a generalist perspective, I think sometimes the more you can kind of see through the forest and the trees. And when it gets a little bit cloudy, you know, have some sense of, "Well, maybe this might happen or maybe that might happen." So I really am a big believer in liberal arts education. I think it's better - particularly in these kind of uncertain times - to know a little bit about a lot of things as opposed to being expert in one thing.
