Meditations 12.22

Consider that everything is opinion, and opinion is in thy power. Take away then, when thou choosest, thy opinion, and like a mariner who has doubled the promontory, thou wilt find calm, everything stable, and a waveless bay.

Marcus Aurelius, Meditations 12.22, translated by George Long

Remember that all is but as thy opinion of it, and that is in thy power. Efface thy opinion then, as thou mayest do at will, and lo, a great calm! Like a mariner that has turned the headland thou findest all at set-fair and a halcyon sea.

Marcus Aurelius, Meditations 12.22, translated by C. R. Haines
