In "Like the Flowing River" by Paulo Coelho, there is a story about a pencil.
Below given is the gist of the story.
The Pencil Maker took the pencil aside, just before putting him into the box.
"There are 4 things you need to know," he told the pencil, "before I send you out into the world. Always remember them and never forget, and you will become the best pencil you can be."
One "You will experience a painful sharpening from time to time, but you'll need it to become a better pencil."
Two: "You will be able to correct any mistakes you might make."
