Let it be thy earnest and incessant care as a Roman and a man to perform whatsoever it is that thou art about, with true and unfeigned gravity, natural affection, freedom and justice: and as for all other cares, and imaginations, how thou mayest ease thy mind of them. Which thou shalt do; if thou shalt go about every action as thy last action, free from all vanity, all passionate and wilful aberration from reason, and from all hypocrisy, and self-love, and dislike of those things, which by the fates or appointment of God have happened unto thee. Thou seest that those things, which for a man to hold on in a prosperous course, and to live a divine life, are requisite and necessary, are not many, for the gods will require no more of any man, that shall but keep and observe these things.
