By the time I came down with polio, at first nobody knew whether I ever would walk again or not. One Monday morning, the doctors came in and said to me, “On Friday we are going to ask you to take three steps.” That was the first time I ever remember visualizing. Looking back now, I didn’t realize it then. I worked all week, lying on my bed, thinking what it would be like and how I would somehow manage to take three steps. Friday morning came and somehow I did manage. And that was really the start of my recovery.
