FASTENING FACES IN YOUR MIND
You are still in the company of your new acquaintance. Having applied Rule One successfully, you are sure of his name, and you are conscientiously observing Rule Two, which means you are seizing every opportunity of saying his name aloud. Rule Three comes next, and you are to put it into effect at once. Fasten the Face in Your Mind,
The difference between the man with an excellent memory for faces and the man who constantly mistakes one person for another is not a matter of eyesight or of intelligence- It is a difference in observation. The first man thinks about what he is seeing; the other does not. William P. Sheridan, one of the most celebrated detectives that ever operated in America, developed the "camera eye" to such an extent that he could pick out of a crowd any one of twenty-two thousand criminals whose pictures were on file with the New York police. His secret? He had schooled his mind to register every detail that his eye took in. He had learned to pay attention, to observe.
