New York Times writer Nicholas Kristof on the power of doing good

For every story of destruction, there’s a story of goodwill and compassion. New York Times reporter Nicholas Kristof has traveled the world to put faces and names to disasters and human rights crises, but he’s there to capture the good, too. In his most recent book, A Path Appears, he and is wife Sheryl WuDunn explore altruism, social change and the fact that one person can make a difference.
