At fifteen my mind was directed to study, and at thirty I knew where to stand.

he who will not economize will agonize

With a heavy load and a long journey

Shall I tell you what knowledge is? It is to know both what one knows and what one does not know.

One who is by nature daring and is suffering from poverty will not long be law-abiding. Indeed, any men, save those that are truly good, if their sufferings are very great, will be likely to rebel.

Behave when away from home as though you were in the presence of an honored guest. Employ the people as though you were assisting at an important sacrifice. Do not do to others what you would not like yourself. Then there will be no feelings of opposition to you, whether it is the affairs of a state that you are handling or the affairs of a family.

Knowing something is not as good as liking it. Liking something is not as good as rejoicing in it.
