I have yet to meet a man as fond of high moral conduct as he is of outward appearances.

Do unto others what you want done unto you.

Surely it is the maxim of loving-kindness: Do not unto others that you would not have them do unto you.

First and foremost, be faithful to your superiors, keep all promises, refuse the friendship of all who are not like you; and if you have made a mistake, do not be afraid of admitting the fact and amending your ways.

He who is really kind, can never be unhappy

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.

To understand yourself is the key to wisdom.
