“There is only one way to happiness and that is to cease worrying about things which are beyond the power or our will. ”

“Freedom is the only worthy goal in life. It is won by disregarding things that lie beyond our control.”

“There is but one way to tranquility of mind and happiness, and that is to account no external things thine own, but to commit all to God.”

“To Epictetus, all external events are determined by fate, and are thus beyond our control, but we can accept whatever happens calmly and dispassionately. Individuals, however, are responsible for their own actions which they can examine and control through rigorous self-discipline. Suffering arises from trying to control what is uncontrollable, or from neglecting what is within our power. As part of the universal city that is the universe, human beings have a duty of care to all fellow humans. The person who followed these precepts would achieve happiness.”

“Some things are in our control and others not. Things in our control are opinion, pursuit, desire, aversion, and, in a word, whatever are our own actions. Things not in our control are body, property, reputation, command, and, in one word, whatever are not our actions. The things in our control are by nature free, unrestrained, unhindered; but those not in our control are weak, slavish, restrained, belonging to others. Remember, then, that if you suppose that things which are slavish by nature are also free, and that what belongs to others is your own, then you will be hindered. You will lament, you will be disturbed, and you will find fault both with gods and men. But if you suppose that only to be your own which is your own, and what belongs to others such as it really is, then no one will ever compel you or restrain you. Further, you will find fault with no one or accuse no one. You will do nothing against your will. No one will hurt you, you will have no enemies, and you not be harmed.”

“Man is not worried by real problems so much as by his imagined anxieties about real problems”

“It is our attitude toward events, not events themselves, which we can control. Nothing is by its own nature calamitous -- even death is terrible only if we fear it.”
