The following exercise must be systematically practiced, saying to oneself, “I shall recall exactly the person I saw yesterday, also the street corner where I met him, and what happened to be in his vicinity. I shall draw the whole picture as exactly as possible and shall even imagine the color and cut of his coat and vest.” Most people will find themselves utterly incapable of doing this and will quickly see how much is lacking in their recollections to produce a really lifelike, graphic picture of what they met and experienced only yesterday.
