An Elegant Puzzle

An effective vision helps folks think beyond the constraints of their local maxima, and lightly aligns progress without requiring tight centralized coordination. You should be writing from a place far enough out that the error bars of uncertainty are indisputably broad, where you can focus on the concepts and not the particulars. Visions should be detailed, but the details are used to illustrate the dream vividly, not to prescriptively constrain its possibilities.
