Book excerpt: One of the greatest and most joyful challenges of adult life is to develop skills that make the people around us better off with us than without us. Integrity is a key part of that challenge. We are social animals, aiming not simply to trade but to make a place for ourselves in a community. You don’t want to have to pretend that you feel proud of fooling your customers into believing you could be trusted. The ethical question is: how do people have to live in order to make the world a better place with them than without them? The economic question is: what kind of society makes people willing and able to use their talents in a way that is good for them and for the people around them? The entrepreneurial question is: what does it take to show up in the marketplace with something that can take your community to a different level? In this book, the authors discuss the connections between the ethical, economic, and entrepreneurial dimensions of a life well-lived.
