The Principle of Order

Everything is clean when each thing is in its place. And your books at school, your clothes and toys at home should each have a place which is really its own and which no other thing can claim. Otherwise, battles will follow and your books will get torn, your clothes stained and your toys lost. Then it will cost you much trouble and patience to find your way in this muddle and put everything right. Whereas it is so convenient when things are kept in order.
The life and work of men, and even the wealth and prosperity of nations, all depend on this same principle of order.
