A child may feel sure of himself as he schemes his schemes. When he was a little boy, my son used to devise great plans for fighting off the Russians if they were to come up the mountain. And he was totally serious. But if Russian tanks had ever begun to roll up out of the valley, we would know we were going to be overrun. When the force of reality strikes us with all its drive, our own imaginings are seen in their proper perspective. —Francis Schaeffer, No Little People
