Marcus Aurelius
Meditations 4.25
Try how the life of the good man suits thee, the life of him who is satisfied with his portion out of the whole, and satisfied with his own just acts and benevolent disposition.
Marcus Aurelius, Meditations 4.25, translated by George Long
Try living the life of the good man who is more than content with what is allotted to him out of the whole, and is satisfied with his own acts as just and his own disposition as kindly: see how that answers.
Marcus Aurelius, Meditations 4.25, translated by C. R. Haines
