Wall Street Journal reporter Amy Dockser Marcus began her media career as a 12-year-old columnist for her hometown (Lexington, Mass.) weekly newspaper. She believes that journalism is a tool that empowers people, especially those outside the system. Marcus says her years of trauma coverage have made her more compassionate: "The essence of telling these stories is to be humble. My obligation is to bring issues to light and to help people look at things in a new way."
