This is why alchemy exists,” the boy said. “So that everyone will search for his treasure, find it, and then be better than he was...
Lead will play its role until the world has no further need for lead;
and then lead must turn itself into gold.
That’s what alchemists do.
They show that, when we strive to become better than we are,
everything around us becomes better, too.”
— Paulo Coehlo, The Alchemist
