Question

One day a monkey went to the nest of his Goose and found there an egg all yellow and glittering. When he took it up it was as heavy as lead and he was going to throw it away, because he thought a trick had been played upon him. But, on second thought, he took it home and soon found to his delight that it was an egg of pure gold. Every morning the same thing occurred, and he soon became rich by selling

his eggs. As he grew rich he grew greedy; and thinking to get at once all the gold the Goose could give, he killed it and opened it only to find nothing.
What is the moral of the story

Answer 1

the moral of the story is to never be greedy because end of the day you will always have nothing

Answer 2

I'm assuming this is just a twist of the Goose and the golden egg story, but the moral is "Those who have plenty want more and so lose all they have."
