Be faithful and true of word; let thy walk be plain and lowly: thou wilt get on, though in savage land. If thy words be not faithful and true, thy walk plain and lowly, wilt thou get on, though in thine own home? Standing, see these words ranged before thee; driving, see them written upon the yoke. Then thou wilt get on.

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

Friendship with the upright, with the truthful and with the well informed is beneficial. Friendship with those who flatter, with those who are meek and who compromise with principles, and with those who talk cleverly is harmful.

A heart set on love will do no wrong.

If you try to do too much, you will not achieve anything.

If the gentleman is not serious, he will not be respected, and his learning will not be on a firm foundation. He considers loyalty and faithfulness to be fundamental, has no friends who are not like him, and when he has made mistakes, he is not afraid of correcting them.

Choose a job you love, and you will never have to work a day in your life.
