Mount Everest is such an amazing laboratory and training ground for leaders and teams. The level at which you must communicate, lead, problem solve, build trust, and deal with change and risk is phenomenal. If you are looking for it you can see great examples of amazing leadership and teamwork and shocking displays of ineffective leadership and total lack of team. If you look closer you can easily see the factors that create success and failure.
When we face risk, we learn about ourselves. We may learn what our limitations are but, most importantly, we learn about what our limitations ARE NOT. This can free us to try new things and to be more successful than we were before.
