With so many social challenges facing our world, trying to effect change feels daunting. The problems are complex, the politics murky, and the players innumerable. Yet, every day there are regular heroes making a significant impact on our most intractable social issues. Can t Not Do is a catchphrase for the urge that captures the heart of effective social change agents explaining, in their own words, their passion and drive: I can't not do this. It's not that I can do this, it's that I can't not. I could not imagine not doing something about this issue. The surprising truth from the trenches is: we already have numerous proven solutions for our many social challenges; what our world needs most, and what most changes our children's future, are more people prepared and committed to act on their social impulses for the long haul. Innovation helps. Money helps, too. But greater numbers of committed people help the most. If you feel an internal, persistent call to do more for the world, Can't Not Do will help you to bridge the gap between wanting to do and doing to access the drive of an effective change agent, to break through self-imposed barriers, to learn key principles for success, and to start seeing yourself acting as a change agent. There is no secret sauce someone is born with and no special club needed to be successful at social change. Rather, successful change agents share some fundamental orientations to the world and to their committed cause and, over time, learn certain lessons that help them become more effective.
