如何改变世界：用商业手段更好地解决社会问题

The stories in the book highlight remarkable individuals, but I'm curious what sparked the author's interest in these particular figures and their methods.

The examples of successful ventures really made me think about the potential for change. Has this book inspired others to take action in their communities?

The selection of case studies feels very deliberate, but I wonder what criteria or process was behind choosing these particular stories over others.
