One of my favorites among the many definitions of resilience is – Positive adaptation to perceived adversity. What Marcus Aurelius is pointing out is that adaptation is learned behavior; true for individuals, communities and nations. We learn to cope by coping; we learn to adapt by adapting to those things we cannot change. If we never have to cross barriers we will never learn to hurdle them. We need to fall if we are to learn how to get back up. In that sense, adversity becomes the primer for resilience. Just as a child’s primer started us on our journey to literacy, adversity starts us on our journey to resilience.
