The real development I've seen of people in organizations, especially in big ones, comes from their being volunteers in a nonprofit organization -- where you have responsibility, you see results, and you quickly learn what your values are. There is no better way to understand your strengths and discover where you belong than to volunteer in a nonprofit. That is probably the great opportunity for the social sector -- and especially in its relationship to business.
