And when he grew up, his father told him:

– My son, not everyone is born with wings. And while it is true that you have no obligation to fly, I think it would be painful if you limited yourself to walking with the wings that the good Lord has given you.

"But I don't know how to fly," answered the son.
"Come," said the father.
He took him by the hand and walking took him to the edge of the abyss in the mountain. – You see son, this is the void. Whenever you want you can fly. You just have to stand here, take a deep breath, and jump into the abyss. Once in the air you will spread your wings and fly...
The son hesitated.
– What if I fall?
"Even if you fall, you won't die, just a few bruises that will make you stronger for the next attempt," the father replied.
The son returned to the town, to his friends, to his peers, to his companions with whom he had walked all his life.
The smallest of mind said:
- Re crazy?
- So that?
– Your father is delirious…
– What are you going to look for flying?
– Why don't you stop fooling around?
– And besides, who needs?

The most lucid also felt fear: – Could it be true?

– Isn't it dangerous?
- Why do not you start slowly?

– In any case, try throwing yourself from a ladder.

– …Or from the top of a tree, but… from the top?
The young man listened to the advice of those who loved him.
He climbed to the top of a tree and courageously jumped...
He spread his wings.
He waved them in the air with all his might... but still... he fell to the ground... With a big bump on his forehead, he ran into his father:
- You lied to me! I can not fly. I tried, and look at the blow I gave myself! I'm not like you. My wings are for decoration… - she whimpered.
- My son - said the father - To fly you have to create the space of free air necessary for the wings to unfold.
It's like jumping on a parachute… you need a certain height before you jump.
To learn to fly you always have to start by taking a risk.
If you want to take risks, it is best to resign yourself and continue walking as usual. 
And you, will you continue walking or do you prefer to take risks and learn to fly?
