The Goose and the Golden Egg
There once was a farmer in a remote region who had a goose that consistently lay golden eggs. The farmer was ecstatic and couldn't believe his good fortune. If I can simply acquire all the golden eggs at once, I'll be rich beyond my wildest dreams, he reasoned to himself.
In order to determine if there were any golden eggs within, the farmer made the decision to cut open the goose. However, he discovered no golden eggs at all when he cut up the goose. He actually found nothing very noteworthy. The golden eggs were a gift from the goose, not something it had kept inside of itself, and the poor creature was just a plain ordinary goose.
The farmer felt let down and realized it had been a mistake to attempt to gather all of the golden eggs at once. The exact object that had originally been supplying him with the golden eggs had been destroyed by him.
Don't kill the goose that lays the golden eggs, is the story's lesson. In other words, resist the urge to rush to acquire everything at once out of greed. Since trying to collect everything at once might occasionally cause issues, it is preferable to remain patient and proceed gently.
