Emperor of Rome Marcus Aurelius

Labor not as one who is wretched, nor yet as one who would be pitied or admired; but direct thy will to one thing only—to put thyself in motion and to check thyself, as the social reason requires

If thou art able, correct by teaching those who do wrong; but if thou canst not, remember that indulgence is given to thee for this purpose. And the gods, too, are indulgent to such persons; and for some purposes they even help them to get health, wealth, reputation; so kind they are. And it is in thy power also; or say, who hinders thee

Simple and modest is the work of philosophy. Draw me not aside to insolence and pride
