“When you are disturbed by events and lose your serenity, quickly return to yourself and don't stay upset longer than the experience lasts; for you'll have more mastery over your inner harmony by continually returning to it.”
― Marcus Aurelius, Meditations

“All striving comes from lack, from a dissatisfaction with one's condition, and is thus suffering as long as it is not satisfied; but no satisfaction is lasting; instead, it is only the beginning of a new striving. We see striving everywhere inhibited in many ways, struggling everywhere; and thus always suffering; there is no final goal of striving, and therefore no bounds or end to suffering.”
― Arthur Schopenhauer, The World as Will and Representation, Volume I

“My formula for greatness in a human being is amor fati: that one wants nothing to be different, not forward, not backward, not in all eternity. Not merely bear what is necessary, still less conceal it—all idealism is mendaciousness in the face of what is necessary—but love it”
― Friedrich Nietzsche, On the Genealogy of Morals / Ecce Homo

“Perfection of character is this: to live each day as if it were your last, without frenzy, without apathy, without pretence.”
― Marcus Aurelius, Meditations
