People with ADD are always reacting. Even when they look calm and sedate, they are usually churning inside, taking this piece of data and moving it there, pushing this thought through their emotional network, putting that idea on the fire to burn, exploding or subsiding, but always in motion. Such hyperreactivity enhances creativity because it increases the number of collisions in the brain. Each collision has the potential to emit new light, new matter, as when subatomic particles collide.
