From "Achieving Sustainability: Visions, Principles, and Practices"According to Gregory Dees, social entrepreneurs play the role of change agents in the social sector through five actions: 1) Adopting a mission to create and sustain social value, 2) Recognizing and relentlessly pursuing new opportunities to serve that mission, 3) Engaging in a process of continuous innovation, adaptation, and learning, 4) Acting boldly without being limited by resources currently in hand, and 5) Exhibiting heightened accountability to the constituencies served and for the outcomes created.
