There is an old fable from Aesop about a man who called his sons to his sick bed. "I am about to die," he said. "In my vineyard lies a treasure. Dig and you will find it." Not long after that, the man dies. The sons busily went to work digging in the vineyard. After they finished their repeated digging, they concluded there was no treasure. The next season, due to the digging, the good ground allowed the vineyard to produce more than it ever had before. There truly is a treasure for those who are willing to work.
