As a leadership consultant, I often find myself in the role of a trusted partner with whom clients confide. Certain stories in particular capture my attention because I have heard them from so many different people, across industries, and around the world. One such recurring theme is around appreciation, a human expression that is powerful, multidimensional, and as I have come to believe, misunderstood and underappreciated. And I have been reflecting on how acts of “appreciation” are investments powered by vulnerability as the currency.
