A little bit of good can turn into a whole lot of good when fueled by the commitment of a social entrepreneur.

Philanthropy is all about making a positive difference in the world by devoting your resources and your time to causes you believe in. In my case, I like to support causes where "a lot of good comes from a little bit of good," or, in other words, where the positive social returns vastly exceed the amount of time and money invested.

My views tend to be centrist. I'm not a big fan of George W., but my politics tend to be more Republican than not.

Participant (Productions) is the only production company in town that has a double bottom line: social good plus financial returns. It's too early to tell how our returns are going to look - though all signs are promising - but social good is what we're really after.

The goal here is to build a brand around social relevance in media (with his Participant Productions company).

Business skills, when well applied, can do more than just make money. They can potentially make money and do some real good, which is immensely satisfying. To do that, it's important to think outside the box, take risks, and be an entrepreneur.

The pace at eBay was frantic and urgent. We knew that if we didn't move fast, somebody would come into the market and quash us. Participant doesn't make a lot of sense from a financial investment perspective, so it's unlikely that other people will be approaching the business in the same way. So you see less urgency; you see a thoroughness and willingness to spend extra time to get things right. Which I think is really important.
