An excellent illustration of the use and value of visualization in
learning and remembering was given by an old captain of a Mississippi
River steamer. "Do you know how I learned the river," he asked; "well I
just lay in bed nights and made a picture in my mind of the river and
the course I had to steer. Then I would go over the picture and see
every detail of it and review it several times. I'd sail up and down
that river several times each night, I'd see every landmark and every
danger point on each trip. That's the way I learned it and I became
a captain when I was younger than many men who had sailed the river
longer than I had."
