“One of the newest figures to emerge on the world stage in recent years is the social entrepreneur. This is usually someone who burns with desire to make a positive social impact on the world, but believes that the best way of doing it is, as the saying goes, not by giving poor people a fish and feeding them for a day, but by teaching them to fish, in hopes of feeding them for a lifetime. I have come to know several social entrepreneurs in recent years, and most combine a business school brain with a social worker's heart. The triple convergence and the flattening of the world have been a godsend for them. Those who get it and are adapting to it have begun launching some very innovative projects.”

“Social entrepreneurs are not content just to give a fish or teach how to fish. They will not rest until they have revolutionized the fishing industry.”

“I once heard Jerry Yang, the cofounder of Yahoo!, quote a senior Chinese government official as saying, "Where people have hope, you have a middle class." I think this is a very useful insight. The existence of large, stable middle classes around the world is crucial to geopolitical stability, but middle class is a state of mind, not a state of income. That's why a majority of Americans always describe themselves as "middle class," even though by income statistics some of them wouldn't be considered as such. "Middle class" is another way of describing people who believe that they have a pathway out of poverty or lower-income status toward a higher standard of living and a better future for their kids.”

“Almost all the students who make it to Caltech, one of the best scientific universities in the world, come from public schools. So it can be done.”

“Communism was a great system for making people equally poor - in fact, there was no better system in the world for that than communism. Capitalism made people unequally rich.”

“At the end of the day, no amount of investing, no amount of clean electrons, no amount of energy efficiency will save the natural world if we are not paying attention to it - if we are not paying attention to all the things that nature give us for free: clean air, clean water, breathtaking vistas, mountains for skiing, rivers for fishing, oceans for sailing, sunsets for poets, and landscapes for painters. What good is it to have wind-powered lights to brighten the night if you can't see anything green during the day? Just because we can't sell shares in nature doesn't mean it has no value.”

“Over the past century, researchers have studied business entrepreneurs extensively..In contrast, social entrepreneurs have received little attention. Historically, they have been cast as humanitarians or saints, and stories of their work have been passed down more in the form of children's tales than case studies. While the stories may inspire, they fail to make social entrepreneurs' methods comprehensible. One can analyze an entrepreneur, but how does one analyze a saint?”
