τὸ λακωνίζειν πολὺ μᾶλλόν ἐστιν φιλοσοφεῖν ἢ φιλογυμναστεῖν
From LSJ
μὴ τὴν ὄψιν καλλωπίζου, ἀλλ' ἐν τοῖς ἐπιτηδεύμασιν ἴσθι καλός → Don't beautify your face, but be beautiful in your habits (Thales, in Diog. Laertius 1.37)
Greek to English
to behave like a Lacedaemonian is much more to love wisdom than to love gymnastics, the Spartan cult is much more the pursuit of wisdom than of athletics (Plato, Protagoras 342e6) ==Modern Greek— καλύτερα λακωνίζει κανείς φιλοσοφώντας παρά ασκώντας τη γυμναστική
