Alison Levine’s On The Edge has been miscast as a book about leadership principles. It is far more than that. The book recounts compelling stories about remarkable human achievements—Ms. Levine’s achievements, mostly—through which one may glean more than business or leadership lessons, and more of what I regard as life lessons that apply beyond sports and business environments. Along the way while reading about Ms. Levine’s adventures and tribulations toward achieving the Adventure Grand Slam, you will absorb life lessons like: do the right thing—always; show up prepared for whatever lies ahead; complacency will kill you; develop strong relationships; find ways to bring out the best in others; you are not special; it’s not always about you, but about those to whom you are accountable; empower those around you; progress doesn’t always look like progress; and own your failures and learn from them. It’s easy enough to read that list and say, “yeah, seems like a sensible list, I got it.” But absorbing these life lessons by traveling along on Ms. Levine’s journeys helps make them unforgettable and a part of you. (And, by the way, if you read about Ms. Levine’s adventure achievements and you think you know someone who’s accomplished more, I’d like to meet him or her.)The lessons that Ms. Levine conveys would benefit people of all walks of life: mothers & fathers; teenagers & college students; those just beginning careers of any kind and those much further down the path. Heck, have your youngsters try it. Please. In our era of domination by “millennials,” it behooves us to help young people begin to learn the life lessons that Ms. Levine conveys. Perhaps the members of the everyone-gets-a-trophy-for-showing-up generation will appreciate that leadership and achievement are not about what I can accomplish for me, but about how I can bring along others for broader achievement. (Now get off my lawn!)Part of the appeal of On The Edge is the force of Ms. Levine’s character, outlook and relatability. And all one has to do to confirm this view is troll the hundreds of Twitter raves about Ms. Levine’s personal appearances and speeches given about the same themes in her book. Or, you could be fortunate enough to attend one of her presentations. The comments from audiences as diverse as the Girl Scouts, West Point cadets, conventions and corporation audiences attest to the wide appeal of her story, message and personality.I mentioned relatability. The book is neither pedantic nor overbearing nor preachy. It’s easy to read, and the adventure stories keep it moving along. And Ms. Levine is relatable, too. Relatable like sitting down for a soda with Thor or Iron Man and talking about what they’ve been up to.Perhaps this recommendation comes a few weeks too late, as high school and college graduation season has just about passed us now. But for all those with the laudable practice of bestowing Dr. Seuss’s “Oh, The Places You’ll Go” on your favorite recent grad, I suggest you now give two books: Dr. Seuss, of course, and Alison Levine’s “On The Edge.” Two are great guidebooks for a most excellent adventure.
