It requires courage to voice your vision, to stand up for it, and to battle the resistance you’ll inevitably face in return, because an effective vision by definition has to be original, and therefore to some degree be provocative, maybe even slightly controversial, according to Rob-Jan de Jong in his book Anticipate: The Art of Leading by Looking Ahead. That is one of the reasons why leaders are often reluctant to espouse a compelling vision, and yet vision casting is one of the key components of effective leadership.
