Curt Rosengren, at Occupational Adventure, has a great series of posts under his category called Making A Difference. I may try to post to some of these individually later, but for now, take a look at the set of them.
Great writing and thinking as usual from Curt!

Before specializing as a professional coach in 2004, I spent more than a decade in leadership, management and program development for state and local government and non-profit organizations. Now I get to help leaders and teams have more clarity and ability to stand up for what's important in their work and in their organizations. Working with me, leaders and teams find more meaning and purpose, feel happier and more confident, navigate change and conflict, and work together better.
