Picasso would never have created cubism without his partner, Georges Braque. In fact, many of their pictures were not signed. If it weren't for their alliance, there wouldn't be Cubism. And there would not have been psychoanalysis had their not been Jung and Abaraham and Jones and a few others who made up Freud's Circle. When you look at history, please keep in mind that it's always a small group of thoughtful and committed people that have changed the world.
Most committees are a waste of time, a lame excuse for lack of action and decision.
The trouble is that most of us have suffered through aindess committee meeting where the leader wasn't clear about the purpose and the members wondered what they were doing there. Bad committee meetings are far worse than no conunittee meetings. It's used extensively to micromanage big projects. It also leads to personal growth for group members. I couldn't have said it better myself.
