Sometime ago there appeared in a newspaper a cartoon showing two fields divided by a fence. Both fields were about the same size and each had plenty of the same kind of grass, green and lush.
In each field there was a mule, and each mule had his head through the fence eating grass from the other mule’s pasture. All around each mule in his own field was plenty of grass, yet the grass in the other field seemed greener or fresher, although it was harder to get.
And in the process the mules were caught in the wires and were unable to extricate themselves. The cartoonist put just one word at the bottom of the picture—“DISCONTENT.”
