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.
