Epictetus (Ἐπίκτητος) was a Hellenic Stoic philosopher. He was born around 55 AD as a slave at Hierapolis, Phrygia (present day Pamukkale, Turkey). Philosophy, Epictetus taught, is a way of life and not just a theoretical discipline. To Epictetus, all external events are determined by fate, and are thus beyond our control; we should accept whatever happens calmly and dispassionately. However, individuals are responsible for their own actions, which they can examine and control through rigorous self-discipline. His teachings were written down and published by his pupil Arrian in his Discourses. 'The Golden Sayings' collect much of his teachings, and today I would like to share the fragments, which are one-sentence rules to live by, for sure.

I - A life entangled with Fortune is like a torrent. It is turbulent and muddy; hard to pass and masterful of mood: noisy and of brief continuance.
II - The soul that companies with Virtue is like an ever-flowing source. It is a pure, clear, and wholesome draught; sweet, rich, and generous of its store; that injures not, neither destroys.
III - It is a shame that one who sweetens his drink with the gifts of the bee, should embitter God's gift Reason with vice.
IV - Crows pick out the eyes of the dead, when the dead have no longer need of them; but flatterers mar the soul of the living, and her eyes they blind.
V - Keep neither a blunt knife nor an ill-disciplined looseness of tongue.
VI - Nature hath given men one tongue but two ears, that we may hear from others twice as much as we speak.
VII - Do not give sentence in another tribunal till you have been yourself judged in the tribunal of Justice.
VIII - If is shameful for a Judge to be judged by others.
IX - Give me by all means the shorter and nobler life, instead of one that is longer but of less account!
X - Freedom is the name of virtue: Slavery, of vice. . . . None is a slave whose acts are free.
XI - Of pleasures, those which occur most rarely give the most delight.
XII - Exceed due measure, and the most delightful things become the least delightful.
XIII - The anger of an ape--the threat of a flatterer:--these deserve equal regard.
XIV - Chastise thy passions that they avenge not themselves upon thee.
XV - No man is free who is not master of himself.
XVI - A ship should not ride on a single anchor, nor life on a single hope.
XVII - Fortify thyself with contentment: that is an impregnable stronghold.
XVIII - No man who is a lover of money, of pleasure, of glory, is likewise a lover of Men; but only he that is a lover of whatsoever things are fair and good.
XIX - Think of God more often than thou breathest.
XX - Choose the life that is noblest, for custom can make it sweet to thee.
XXI - Let thy speech of God be renewed day by day, aye, rather than thy meat and drink.
XXII - Even as the Sun doth not wait for prayers and incantations to rise, but shines forth and is welcomed by all: so thou also wait not for clapping of hands and shouts and praise to do thy duty; nay, do good of thine own accord, and thou wilt be loved like the Sun.
XXIII - Let no man think that he is loved by any who loveth none.
XXIV - If thou rememberest that God standeth by to behold and visit all that thou doest; whether in the body or in the soul, thou surely wilt not err in any prayer or deed; and thou shalt have God to dwell with thee.
