if your community, at whatever scale you define it, needs to focus on enhancing one skill set, one capacity, one competency to help ensure going forward successfully, choose adaptability.

We wrote this book with three goals in mind: (1) to show that productive change must be adaptive to be sustainable; (2) to offer tools and frameworks that lower risk so people can see how to lead and stay alive through the dangers of change; and (3) to encourage people to seize opportunities to exercise leadership that are within reach every day.
