Just as nature takes every obstacle, every impediment, and works around it--turns it to its purposes, incorporates it into itself, so, too, a rational being can turn each setback into raw material and use it to achieve its goal.

Discard everything except these few truths: we can live only in the present moment, in this brief now; all the rest of our life is dead and buried or shrouded in uncertainty. Short is the life we lead, and small our patch of earth.

Since it is possible that thou mayest depart from life this very moment, regulate every act and thought accordingly. But to go away from among men, if there are gods, is not a thing to be afraid of, for the gods will not involve thee in evil; but if indeed they do not exist, or if they have no concern about human affairs, what is it to me to live in a universe devoid of gods or devoid of Providence? But Gods there are, undoubtedly, and they regard human affairs; and have put it wholly in our power, that we should not fall into what is truly evil.

There is but one thing of real value - to cultivate truth and justice, and to live without anger in the midst of lying and unjust men.

Be not careless in deeds, nor confused in words, nor rambling in thought.

Remember how often you have postponed minding your interest, and let slip those opportunities the gods have given you. It is now high time to consider what sort of world you are part of, and from what kind of governor of it you are descended; that you have a set period assigned you to act in, and unless you improve it to brighten and compose your thoughts, it will quickly run off with you, and be lost beyond recovery.

Reject your sense of injury, and the injury itself disappears.
