"Blessed Unrest" by Paul Hawken (of Smith & Hawken) is just wonderful. A quick encapsulation:
There are tens of millions of ordinary and not-so-ordinary people willing to confront despair, power, and incalculable odds in order to restore some semblance of grace, justice, and beauty to this world.
I have come to these conclusions: this is the largest social movement in all of history, no one knows its scope, and how it functions is more mysterious than what meets the eye.
Paul Hawkens ... Blessed Unrest
Are you one of these tens of millions of people? I trust you are. - Tim
