The great Greek sculptor Phidias had high standards when he was carving the statue of Athena for the Parthenon about 2,400 years ago.
According to an old story, he was busy chiseling the strands of her hair on the back of her head when an onlooker commented, "That figure is to stand 100 feet high, with its back to a wall. Who will ever know what details you are putting behind there?"
Phidias replied, "I will."
Perfectionism or a waste of time? I vote for doing the best you can at every opportunity, regardless of your line of work.
Perhaps because works of art often outlast the artist's life span, such creators are more inclined to strive for utter perfection. When Frederic Auguste Bartholdi completed the Statue of Liberty in the late 1800s, there were no airplanes or helicopters to inspect its detail from the air.
Yet many years later, when helicopters hover close overhead, it is clearly evident that the sculptor meticulously finished every detail of Lady Liberty's coiffure and crown without "cheating" in any area that could not be seen from the ground.
Clearly, Bartholdi was a perfectionist. He wanted to create a thing of beauty that was perfect from every point of view and over any period of time. He did his absolute best because he could. That's a good principle to follow when creating anything of lasting value.
Attitude is central to assessing your ability and pushing it to its maximum. To move from strict perfectionism to the pursuit of excellence, may I recommend you consider these suggestions:
