This cartoon has yielded a phrase I often use when I try some new technical innovation and it does not work. Like this new five button mouse I hooked up to my computer.
One RAF pilot said that before the war he was told by an experienced old hand, "Just remember, no matter how scared you are the other guy is twice as scared as you are." On his first combat against BF-109's over France he thought, "Well, based on how I am feeling, that poor chap over there must be hysterical." and went over and shot down the German.
