Look At Here How An Eagle Can Become A Chicken

A few times ago I read a short story that impressed me very much. I want to repeat it here to you.

A man found an eagle's egg and put it in a hen’s nest.
The egg hatched simultaneously with the brood, and the baby eagle grew along with the chicks.
Throughout its life the eagle did what the backyard chickens did, thinking of being one of them. It rummaged through the soil looking for worms and insects, cackling and shaking its wings rising from the ground a few feet.
The years passed and the eagle grew very old.
One day it saw above it, in the cloudless sky, a beautiful bird that soared, majestic and elegant, in the midst of a strong air current, barely moving his strong golden wings.
The old eagle looked up, startled. "Who is that?" asked.
"It’s the eagle, the king of birds," replied its neighbour.
"It belongs to the sky. We, however, belong to the earth, because we are chickens."
So the eagle lived and died like a chicken, because it considered itself to be such.

This is what I concluded:

"You can fly too, you just have to know it and believe it!"

Draw yourself your own conclusions!
