The Chinese philosopher Chuang Tzu told a story about a farmer who lost his horse. All of his friends in consoling him would say “What bad luck.” He on the other hand would say “How do you know, maybe this is good luck.” A few weeks later his horse returns along with another. Everyone exclaims, “What good news!” and the farmer says “How do you know, maybe this is bad news.” Attempting to train the new horse his son breaks his leg. “What bad news” everyone says. The farmer of course says, “How do you know, maybe this is good news.” A few days later, the country goes to war and the emperor drafts all able-bodied men his son’s age into the army. The farmer’s neighbors say “What good luck!” and of course…. “How do you know?”
