Ludwig von Mises on entrepreneurs as visionaries

What distinguishes the successful entrepreneur and promoter from other people is precisely the fact that he does not let himself be guided by what was and is, but arranges his affairs on the ground of his opinion about the future.  He sees the past and the present as other people do; but he judges the future in a different way.

~ Ludwig von Mises, Austrian economist, Human Action, p. 585, 1949
