Fewer than 50 people have accomplished the Explorer's Grand Slam, a challenge of summiting the highest peaks on each of the seven continents and completing treks to the North and South poles. Colin O'Brady not only completed the EGS this summer, he shattered the world record for it, finishing in just 139 days. O'Brady also set the world record for climbing the seven summits -- summiting Kilimanjaro in just 11.5 hours. Five years ago, a friend suggested he try mediation and recommended a 10-day silent vipassana retreat. At first O'Brady said he looked at meditation like an elite athlete, hoping to train his body and mind for peak performance, but soon discovered meditation gave him a much greater benefit for his daily life.
