The Two Bags

"According to ancient lore, every man is born into the world with two bags suspended from his neck-one in front and one behind, and both are full of faults. But the one in front of his neighbor's faults; the one behind, full of his own. Consequently, men are blind to their own faults but never lose sight of their neighbor's."

From Aesop's Fables, pg. 33
