“You do many things at once; you read, listen to the radio, talk, smoke, eat, drink. You are the consumer with the open mouth, eager and ready to swallow everything—pictures, liquor, knowledge. This lack of concentration is clearly shown in our difficulty in being alone with ourselves. To sit still, without talking, smoking, reading, drinking, is impossible for most people. They become nervous and fidgety, and must do something with their mouth or their hands.”
