Fuller uses the metaphor of a ship's rudder. He says when the rudder of a ship is angled to one side or another, the ship tends to keep rotating beyond the helmsman's intention. He has to correct the rotation, moving it back toward the original direction in a never-ending process of action and reaction, adjustment and correction. Picture that in your mind - a helmsman on a quiet sea, gently guiding his boat toward its destination by coping with thousands of inevitable deviations from its course. It's a lovely image, and it's a wonderful model for the process of living successfully.
