“How to Be Useful” as per 2 Corinthians.
And in common-school education during George III’s reign:
There were no cheap books or newspapers, and no proper system of public instruction. The poor seldom left the counties in which they were born. They knew nothing of what was going on in the world. Their education was wholly of that practical kind which comes from work and things, not from books and teachers; yet many of them with only these simple helps found out two secrets which the highest culture sometimes misses, – how to be useful and how to be happy.
