Be decisive & vigilant. Marcus Aurelius 4.22

Marcus Aurelius reminds himself to stay vigilant. Life requires us to act and react appropriately, with keen insight into our immediate environment. Move decisively, and remember to watch what happens.

Μὴ ἀπορρέμβεσθαι, ἀλλ’ ἐπὶ πάσης ὁρμῆς τὸ δίκαιον ἀποδιδόναι καὶ ἐπὶ πάσης φαντασίας σῴζειν τὸ καταληπτικόν.

Don't let yourself wander. Meet every attack with just defense, and save a vivid memory of each impression that reaches your mind.
