Alison Levine, Polar Explorer

Meet Alison Levine, the only American to follow the route of Reinhold Messner to the South Pole, and one of the few to complete the Adventure Grand Slam--climbing the 7 highest peaks in the world, and skiing to both the North and South Poles. Alison has written a book about leadership with lessons from these extreme environments, called "On the Edge." She tells us what it takes to make it in extreme conditions--and everyday ones.
