Weddell seals lie atop ice at Cape Denison, Commonwealth Bay, East Antarctica, in this picture taken January 1, 2010. At age 34, Rachael Robertson accepted the biggest challenge of her life: to lead a large, 12-month expedition in Antarctica. Two months on, she found herself having to ask the team of 120 how they managed to get through a year's supply of condoms in just eight weeks. Robertson, a former chief ranger for the national parks service in Australia's Victoria state, spoke to Reuters about her book "Leading on the Edge" and how she developed a unique style of leadership using a technique called "no triangles".
