A Decalogue of Canons for observation in practical life:
1. Never put off until tomorrow what you can do today.
2. Never trouble another for what you can do yourself.
3. Never spend your money before you have it.
4. Never buy what you do not want, because it is cheap; it will be dear to you.
5. Pride costs us more than hunger, thirst, and cold.
6. We never repent of having eaten too little.
7. Nothing is troublesome that we do willingly.
8. How much pain have cost us the evils which never have happened.
9. Take things always by their smooth handle.
10. When angry, count ten, before you speak; if very angry, an hundred.
(letter to Thomas Jefferson Smith, 1825)
