A Chinese Zen story, one that I like to share for anyone struggling:
One day a farmer’s mare escaped from the pen. When he discovered this the villagers said, “Oh what terrible luck!”
The farmer said, “We’ll see.”
A few days later the mare returned and brought 6 stallions with her. And the villagers said, “What good luck!”
The farmer said, “We’ll see.”
A few days later the farmer's son was trying to train one of the wild horses, fell off and broke a leg. And the villagers said, “What terrible luck!”
The farmer said, “We’ll see.”
A few days later the Emperor’s men came through the village conscripting young men for the military and the farmers son was rejected because of his broken leg. The villagers said, “What good luck!”
The farmer said, “We’ll see.”
