Human beings water the weeds

"When it comes to agriculture, humans are wise. 
Over the centuries, they cultivated the fruits of the field, 
while removing the weeds. Consequently, we have finer fruits.

Psychologically, it is another story. 
Human beings water the weeds, neglect

the fruits, and wonder at their poverty!"
