To endure is the first thing that a child ought to learn, and that which he will have the most need to know. The person who is slowest in making a promise is most faithful in its performance. The person who has lived the most is not the one with the most years but the one with the richest experiences. One loses all the time which he might employ to better purpose.
Falsehood has an infinity of combinations, but truth has only one mode of being.
Virtue is a state of war, and to live in it we have always to combat with ourselves. The training of children is a profession, where we must know how to waste time in order to save it.
