Phil Randazzo applied for a commission-only job selling fire extinguishers. The interviewer asked him the last personal development book he’d read. When he couldn’t think of one, the man threw a Jim Rohn cassette at him and said, “Get out of my office and don’t come back until you learn to work on yourself!” Years later, he owns Text Safe Teens, an app to prevent people from using cell phones while driving. His online, nonprofit American Dream U helps transitioning military find their dream job or start a business.
