Epicurus Ἐπίκουρος

early 3rd century BC · Athens, ancient Greece

Let no one put off philosophy while young, nor grow weary of it when old. For no one is too early or too late for the health of the soul.

Μήτε νέος τις ὢν μελλέτω φιλοσοφεῖν, μήτε γέρων ὑπάρχων κοπιάτω φιλοσοφῶν· οὔτε γὰρ ἄωρος οὐδείς ἐστιν οὔτε πάρωρος πρὸς τὸ κατὰ ψυχὴν ὑγιαῖνον.

Letter to Menoeceus, in Lives of the Philosophers 10.122

Aphorisms 1.1

A well in sandy ground yields water as deep as you dig; a person's wisdom wells up as much as they learn.
