“This book assumes that you are interested in being part of world-changing human capital that will help solve problems big and small. Maybe you are a teacher or a communicator, an activist or a doctor, a lawyer or an investor, or some new force for positive change. I have seen people like you alter the lives of schoolchildren and street children, refugees, the formerly incarcerated; of people living in forgotten communities and in places ravaged by war, poverty, or toxic industries.”
