“Entrepreneurial quality - is by far the toughest (criterion for a social entrepreneur).. For every one thousand people who are creative and altruistic and energetic, there's probably only one who fits this criterion, or maybe even less than that. By this criterion...we do not mean someone who can get things done. There are millions of people who can get things done. There are very, very few people who will change the pattern in the whole field.”

“The first - the most obvious (test of a true social entrepreneur) - is are they possessed, really possessed by an idea... The idea - making it happen across society - is something they are married to in the full sense of the word. One key test of that is this: Is this an idea that you see growing out of their whole life? I get very, very suspicious when I see someone who had an idea two years ago. It just doesn't ring true. Because with the typical entrepreneur you can see the roots of the interest when they're very young. There's a real coherence to people's lives.”

“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.”

“There are many people who can do big things, but there are very few people who will do the small things.”

“The only people for me are the ones who spill things, the ones who drop their cups sometimes, the ones who get dirty hands and messy hair, the ones who can go barefoot if they feel like it, the people who forget things, and can laugh at themselves every day...”

“Peter, before you can do things for people, you must be the kind of man who can get things done. But to get things done, you must love the doing, not the secondary consequences. The work, not the people.” (578)”

“There are few things less comforting than a tiger who's been up too late.”
