I really strongly believe in the power of the small story, because it is so difficult to do humanitarian work at a global scale. When you zoom out that far, you lose the ability to view people as humans.
Emily Pilloton's TED talk, Teaching design for change, is one of the most inspiring things I've ever seen. In it she tells the story of using integrating design thinking into a small town public school system. In doing so, they not only helped improve the school system, but used it as a way to help the entire community.
