David has helped me many times. I felt honored to host him and, I hope, help start his environmental legacy. We covered two main things. First, his new book, Friend of a Friend, on networking. His background as a professor and practitioner means he approaches networking systematically and practically, so beyond learning to network more effectively, you understand networking as a process. Second, his environmental commitment. I loved his choice for reasons you'll hear when you listen. I believe it will improve his life beyond just living by his environmental values. David is direct, knowledgeable, experienced, and plain-spoken. Enjoy!
