Hesiod

Οὐκ αἰεὶ θέρος ἐσσεῖται· ποιεῖσθε καλιάς.

For full indeed is earth of woes, and full the sea; and in the day as well as night diseases unbidden haunt mankind, silently bearing ills to men, for all-wise Zeus hath taken from them their voice. So utterly impossible is it to escape the will of Zeus.

Ἔργον δ᾽ οὐδὲν ὄνειδος, ἀεργίη δέ τ᾽ ὄνειδος.

But they will give straight judgements to strangers and to the men of the land, and go not aside from what is just, their city flourishes, and the people prosper in it.

Admire a small ship, but put your freight in a large one; for the greater the lading, the greater will be your piled gain, if only the winds will keep back their harmful gales.

Μηδ᾽ ἀναβάλλεσθαι ἔς τ᾽ αὔριον ἔς τε ἔνηφιν·
οὐ γὰρ ἐτωσιοεργὸς ἀνὴρ πίμπλησι καλιὴν
οὐδ᾽ ἀναβαλλόμενος· μελέτη δὲ τὸ ἔργον ὀφέλλει·
αἰεὶ δ᾽ ἀμβολιεργὸς ἀνὴρ ἄτῃσι παλαίει.

The gods have placed sweat as the price of all things.

Ὣς οὐκ ἔστι Διὸς κλέψαι νόον οὐδὲ παρελθεῖν.

He is the best of all who thinks for himself in all things. He, too, is good who takes advice from a wiser (person). But he who neither thinks for himself, nor lays to heart another's wisdom, this is a useless man.’''

Hunger is altogether a meet comrade for the sluggard.

Work the work which the gods ordained for men, lest in bitter anguish of spirit you with your wife and children seek your livelihood amongst your neighbours, and they do not heed you.

Take your fill when the cask is first opened and when it is nearly spent, but midways be sparing: it is poor saving when you come to the lees.

For in misery men grow old quickly.

Οὐ μὲν γάρ τι γυναικὸς ἀνὴρ ληίζετ᾽ ἄμεινον
τῆς ἀγαθῆς, τῆς δ᾽ αὖτε κακῆς οὐ ῥίγιον ἄλλο.

On the tongue of such an one they shed a honeyed dew, and from his lips drop gentle words.
