Α POOR BOY once went to the forest to pick up firewood. After gathering enough and loading the logs on his cart, he thought of talking a walk to get fresh air instead of going straight back home.

As it got dark, however, he thought of starting a fire using the logs. While digging in the ground, he encountered a big "X" spot, from which he realized that a big treasure was buried below. He then took a shovel and dug, imagining all sorts of treasures, like golden coins, diamonds and precious pearls. The more he thought of it, the greater his enthusiasm.

Many hours later he found a chest with a key placed on the keyhole. As soon as he turned it, the chest opened, revealing not diamonds and precious stones, but rather a dusty old tome of more than a thousand pages.

In the book cover, a label was to be found: "The book of knowledge". As for the content? Let each one of us find for his own.
