Man is not worried by real problems so much as by his imagined anxieties about real problems
EpictetusIf anyone is unhappy, remember that his unhappiness is his own fault... Nothing else is the cause of anxiety or loss of tranquility except our own opinion.
EpictetusSome 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 own actions.
