In order to move toward a target, you must first have a target. Listing your priorities, which means wrestling with the choices that define your identity, is the first step. Most successful groups end up with a small handful of priorities (five or fewer), and many, not coincidentally, end up placing their in-group relationships – how they treat one another – at the top of the list. This reflects the truth that many successful groups realize: their greatest project is building and sustaining the group itself. If they get their own relationships right, everything else will follow.
