I had what was called an "overactive mind" as a child. This worried my family and others, especially when taken beyond the reading dictionaries, encyclopedias and whatnot. I also liked to take things apart and put them back together again. For example, not just Tinker Toys, but the kitchen stove, the plumbing, the telephone and clocks -- everything including, to everyone's horror, the piano. I got it all back together, but my Dad had to pay $40 to get it retuned. But I was consumed by discovering how things worked, and was serious and determined in this regard. I made charts and graphs and drawings. Most people don't care how things work. They just use them. And herewith was the beginning of those illustrations and graphs and box-and-flow charts which many years later were dragged from Stanford Research Institute into the Pentagon and DIA headquarters and presented to their oversight committees and consulting scientists. Diagrams of how, theoretically at least, the so-called "psychic mind" functions. And herewith was the beginning of my conviction that the quickest way of LEARNING anything was via visual illustrations and diagrams -- not by linear words, which anyway appeal only to the left-hemisphere of the brain and which is said to be the "seat of the intellect."
