An engineer engaged in railroad construction in South America explained to one of the villagers, living alongside the new rail, the advantages it would bring him. Wanting to illustrate his point, he asked the person "How long does it take to carry your produce to market by muleback?"
"Three days." The man replied.
"Then," said the engineer, "you can understand the benefit that road will be to you. You will be able to take your produce to market and return home on the same day."
"Very good," the person agreed courteously. "But senor, what shall I do with the other two days?”
We often complain of being to busy yet feel uncomfortable when the opportunity to rest comes available.
