[I must tell my favorite Asimov story. This is a classic case of motivational manipulation. During his nine months in the Army in 1946, he wanted to avoid the really bad jobs that privates normally get. He could type incredibly fast. So, when he was sent to a new base, on the first day, at 5:05 p.m., he walked into the typing pool’s office and asked the desk sergeant if he could use a typewriter to type a letter to his wife. “Sure, soldier,” was the reply. He put a piece of paper in the machine and started to type, which he did at 80 WPM or so. The sound carried across the empty room. The sergeant was at his side within minutes. “Say, soldier, we could use someone like you in this office. Would you like to sign up?” Poor, naive Isaac the grunt said, “I guess so, sergeant. I just got to this post. You’ll have to contact my commanding officer. I haven’t been assigned to anything yet.” Done. He made it to corporal this way.]
