Masha Gordon, a mountaineer who completed the seven summits and both poles in record time, ventured to take lessons in grit from the boardroom to the most challenging terrain on earth. Thirty minutes from the summit of Everest she was faced with an executive decision: should she risk getting caught in a storm and possibly putting her life in peril or divest and live to see another day? Luckily the risk was worth taking, but the tough mindedness she earned in business made her decision a sound one. Learn how doing great things has taught Gordon how little it actually takes to be happy and successful.   Lessons:     1.    Even when you invested a large amount in an experience the smartest thing could be to divest if it means living to see another day.     2.    Move counter to stereotypes so that they no longer define you.     3.    Let a healthy fear and respect complement the excitement of your expeditions.
