So much of life depends on your perspective and I have found this story inspiring to help me look at life in a different way:
There is a story of a Chinese farmer who used an old horse to till his fields. One day there was a massive storm and the horse was spooked, he broke down the fence and escaped into the hills. When the neighbors heard what had happened, they sympathized with the farmer about his bad luck, but the old man only replied, "Bad luck? Good luck? Who knows?"
A week later, the old horse returned with a herd of wild horses from the hills and this time the neighbors congratulated the farmer on his good luck. His reply was, "Good luck? Bad luck? Who knows?"
When the farmer's son was attempting to tame one of the wild horses, he fell off its back and broke his leg and once again the neighbours consoled the old farmer about his bad luck, but his only reaction was, "Bad luck? Good luck? Who knows?"
Some weeks later, the army marched into the village and conscripted every able-bodied youth to go and fight against a neighbouring kingdom. When they saw the farmer's son with his broken leg, they left him.
Now was that good luck or bad luck?
