What hardships does the eagle need to go through to become the air overlord?

I found this online. I've seen it before. It's amazing.

The eagle is the oldest bird in the world. Its life span can reach 70 years.

But to live such a long life, you must make difficult but important decisions at the age of forty!

When the eagle lived to be forty years old, its claws began to age and it could not catch its prey effectively.

Its peck became long and curved, almost touching its chest.

Its wings become heavy because its feathers grow thicker and thicker. This makes flying very difficult!

It has only two options:

1. Wait for death, 2. Go through a very painful process of transformation-150 days of long magic training.

It must fly very hard to the top of the mountain. Nest on the cliff.

Stay there. No flying.

The eagle hit the rock with its beak until its beak fell off completely.

Then wait quietly for the new beak to grow.

Then, it will pull out the nails one by one with its newly grown beak.

When new nails grow, they will pull out feathers one by one.

Five months later, new feathers came out.

The eagle began to fly. Go back to the sculpture for 30 years!

In our life, sometimes we have to make difficult decisions.

Start the update process.

We must abandon old habits and old shackles.

So that we can fly again. Hehe, the eagle is painful and happy. . . .
