Who really said it
Live each day as if it were your last
This one is real in substance and loose in wording. Marcus writes the thought at least three times in the Meditations: at 2.5 (‘do every act of thy life as if it were the last’), at 7.69 (‘the perfection of moral character consists in this, in passing every day as the last’) and at 2.11 (‘since it is possible that thou mayest depart from life this very moment, regulate every act and thought accordingly’). What he never writes is the seven-word slogan — and the slogan quietly deletes the condition he always attaches.
