Greg Mortenson: Five Cups of Hope, Heart, and Humility

Greg Mortenson

Greg Mortenson -- author of the mega-best-selling Three Cups of Tea and the powerful sequel, Stones into Schools -- wields so much global influence and enjoys such rock-star adulation that I could understand if he were a pompous and arrogant guy. But in fact, as I discovered a month ago when I interviewed him onstage at National Geographic in Washington, DC, he's one of the most humble power-brokers on the planet.
