PARABLE OF THE PENCIL
The Pencil Maker took the pencil aside, just before putting him into the box. "There are five 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 be able to do many great things, but only if you allow yourself to be held in Someone's hand.
TWO You will experience a painful sharpening from time to time, but you'll need it to become a better pencil.
THREE You will be able to correct any mistakes you might make.
FOUR The most important part of you will always be what's inside.
FIVE On every surface you are used on, you must leave your mark. No matter what the condition, you must continue to write.
