A dog had stolen a piece of meat out of a butcher shop and was crossing a river on his way home when he saw his own shadow reflected in the water below.
Thinking that it was another dog with another piece of meat, he became intent on capturing the other piece as well. Once he snapped at the treasure below, however, he dropped the prize that he was carrying and thus lost everything he had.
Old Learning: Grasp at the shadow and you will lose the substance.
Understanding need and want is critical. Need brings out the best and want makes you the worst.
