First, great leadership often starts in community. When facing great odds or forced to deal with unusual or trying circumstances, few of us are fortified enough to act alone, without counsel or support. This is a point often hammered home by Harvard Business School professor and former Medtronic CEO Bill George, who is a vocal advocate for what he calls “True North Groups.” These are gatherings of peers and mentors with whom we can share. They can counsel us as we face difficult problems and hold us accountable for acting in accordance with our values. Others have advocated similar constructs, such as a personal board of directors. And I’ve noted before the measurable benefits of mentorship. In short, no man is an island, and we are better leaders when we are rooted in a community empowered to counsel us, challenge us, and hold us accountable.
