Seventeen-year-old Lucy Westlake is an accomplished mountain climber (she started at age 7) who is the youngest female to have ascended the highest peaks in all 50 U.S. states. But you can’t have a peak without a valley – and Lucy also describes the low points she’s faced in learning this resonant truth: the ideal way to build resilience is overcoming small failures, so that when the big ones come – and they will -- we have a reservoir of grit to keep climbing.     To learn more about Lucy Westlake, visit www.lucywestlake.com   To explore Crucible Leadership resources, and to pre-order Warwick Fairfax's book, CRUCIBLE LEADERSHIP: EMBRACE YOUR TRIALS TO LEAD A LIFE OF SIGNIFICANCE, visit www.crucibleleadership.com
