Ἕωθεν προλέγειν ἑαυτῷ: συντεύξομαι περιέργῳ, ἀχαρίστῳ, ὑβριστῇ, δολερῷ, βασκάνῳ, ἀκοινωνήτῳ: πάντα ταῦτα συμβέβηκεν ἐκείνοις παρὰ τὴν ἄγνοιαν τῶν ἀγαθῶν καὶ κακῶν. → When you wake up in the morning, tell yourself: The people I deal with today will be meddling, ungrateful, arrogant, dishonest, jealous, and surly. They are like this because they can't tell good from evil. | Say to yourself in the early morning: I shall meet today inquisitive, ungrateful, violent, treacherous, envious, uncharitable men. All these things have come upon them through ignorance of real good and ill.
