There once was a farmer and his wife who owned a goose that laid a golden egg every day. These eggs made the couple very rich, but they soon grew impatient and greedy. They thought, "If this goose lays golden eggs, she must be full of gold inside. If we kill her, we can get all the gold at once."

So, they killed the goose.
 

But to their dismay, they found that she was just like any other goose inside — no gold, no treasure. They had destroyed the source of their wealth out of greed and impatience.
 

Moral of the Story:

Greed can lead to loss. Or in other words, don't kill the goose that lays the golden eggs.

It's often used as a cautionary tale about the dangers of short-sightedness and excessive desire for quick gains.

In fitness, patience pays. Trying to rush results can lead to setbacks. Like the goose that laid golden eggs, consistent effort gives you lasting rewards — if you let it.
