Scott Harrison went from nightclub promoter to founder of charity: water. His mission? To bring clean water to millions of people around the world. He describes himself as a "prodigal son" who left his conservative Christian home to climb New York City's social scene and opens up about his epiphany to turn his life around. He explains the nonprofit's promise to allocate 100% of public donations directly to fund clean water projects and how a lack of access to clean water contributes to gender disparity in developing nations.
