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.
