I found this neat quote on the Integral Leadership Review web site
Greatness in leadership, that is, human authenticity, is not only a matter for individuals. Quite to the contrary, it is best accomplished in groups and leads therefore to in-depth group growth and to team development. Group and individual growth are systemically interrelated.
People must share with each other their experiences of authentic behavior, their inner struggles, their successes, what makes them proud, their tough decisions, and then support one another in this process of growing as a person and growing as a team.
It pretty much sums up what we do during our 12 week GROW:leadership pgms
