A wealthy couple desired to employ a chauffeur. The wife advertised, the applicants were screened, and (4) candidates were brought to her for the final selection. She called the prospective men to her balcony and pointed out a brick wall alongside the driveway. She asked the men, "How close do you think you could come to that wall w/out scratching my car?"
The 1st man felt he could drive w/in a foot of the wall w/out damaging the car. The 2nd felt sure he could come w/in (6) inches. The 3rd believed he could get w/in (3) inches. The 4th candidate said, "I do not know how close I could come to the wall without damaging your car. Instead, I would try to stay as far away from that wall as I could."
This candidate had a different focus. He understood that true skill in driving is not based so much on the ability to steer the car to a narrow miss as on the ability to keep a wide margin of safety.
