Here are a couple of quotes I found from another site.
The job of a social entrepreneur is to recognize when a part of society is stuck and to provide new ways to get it unstuck. He or she finds what is not working and solves the problem by changing the system, spreading the solution and persuading entire societies to take new leaps.
"Social entrepreneurs identify resources where people only see problems. They view the villagers as the solution, not the passive beneficiary. They begin with the assumption of competence and unleash resources in the communities they're serving."
David Bornstein, author of How to Change the World: Social Entrepreneurs and the Power of New Ideas
