Respect yourself if you would have others respect you.

Never participate in the secrets of those above you; you think you share the fruit, and you share the stones - the confidence of a prince is not a grant, but a tax

Never lose your self-respect, nor be too familiar with yourself when you are alone. Let your integrity itself be your own standard of rectitude, and be more indebted to the severity of your own judgment of yourself than to all external percepts. Desist from unseemly conduct, rather out of respect for your own virtue than for the strictures of external authority.

Many get the repute of being witty but thereby lose the credit of being sensible. Jest has its little hour, seriousness should have all the rest.

It is impossible to live without brains, either one's own or borrowed.

Wisdom is immortal. She can wait forever, but you cannot.

The happy are an exception who enjoy innocently their simple happiness.
