When I left my accounting practice in 2011, I was asked what I hoped to accomplish by writing books about the continuing success of my colleagues. I said that I intended to define the growth imperative for my profession for the next 75 years. A growth imperative, any given profession's reason to grow, is ultimately where succession lives—society needing us more every year than it did the last. As people, the relevance and meaning of our lives hinge on our persistence in providing social mobility to ourselves and one another. We do this by buying, selling, and consuming one another's goods and services in meaningful ways that create a pattern of rising growth. And we are no different from any other part of the economy today in search of the holy grail of personal and organizational growth.
