From a solid interview with Seth Godin linked below:
I would say that I’m inspired by two things. The first is the opportunity. This is the first time in human history that somebody sitting in their living room has a chance to contact more than just a couple of people at a time. And more important than that, the revolution that’s going through our world right now is opening more doors for more people than ever before. When I look at the combination of those two things, I see an opportunity, and I wake up every morning hoping I won’t waste it.
