It is important to distinguish a vision from illusion and utopias. Utopias and illusions are unreal imaginings without a functional basis, which through embellishments and fantasies a false ideal image. A vision, on the other hand, is formed from motivating ideas of a certain actual state and often pursues a strategic goal. As a draft of the future, it describes future situations and processes. Through a comprehensible reference to reality, based on credible forecasts, a vision can act as a means, to influence other people, to inspire or to accelerate actions.
