No bad vibes. Marcus Aurelius 5.2

Marcus advises himself to avoid obsessing over bad appearances, fantasies, imaginations, dreams. A real problem must be met with action that is harder if we waste energy imagining what we fear.

Ὡς εὔκολον ἀπώσασθαι καὶ ἀπαλεῖψαι πᾶσαν φαντασίαν τὴν ὀχληρὰν ἢ ἀνοίκειον καὶ εὐθὺς ἐν πάσῃ γαλήνῃ εἶναι.

Calmly dismiss and delete every dream that is irksome or uncouth, and be immediately at peace.
