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.

I believe that Silicon Valley is truly a place of excellence and the impact of this tiny community on the world is completely disproportionate to its size. We are the undisputed leaders of technological change. But with our abundance of talent and resources, we also have the opportunity to be the pioneers of social change and, ultimately, this may be our greatest contribution.

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

I was living in a house with five guys, eating their leftovers when they weren't watching. I went from that to having $1-billion-plus on paper.

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.

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