For those who get the urgency of our day, here are Tom Peterson's "things to think about" if you want to change the world. The call for audacity. The power of a bold goal. How ideas emerge and spread. The daily slog. How to grow your cause. Creating a mighty message. Brands, names, symbols. Exploring growth possibilities. Finding and creating community. And taking on the ogres that guard against progress. Especially helpful for nonprofit leaders.
