I recently completed my third 4th Musketeer, Extreme Character Challenge in the Drakensberg with a bunch of great men. During those 72 hours, more than 220 men were challenged to bridge the 250mm gap between their hearts and their heads. What I took out of this round is different than from the previous two, and that is that every face has a pool of tears, and that every man (and woman) has a story that makes them unique, if we just take time to engage. The larger population grew up believing that personal problems are to be sorted out privately and men in general are ashamed to ask for assistance. “I'm the man, I don't need help! I have this sorted!” We believe that asking for assistance show signs of weakness, allowing others to step on and walk over us.
