Ἄλλοτε μητρυιὴ πέλει ἡμέρη, ἄλλοτε μήτηρ. - Hesiod

Ὣς οὐκ ἔστι Διὸς κλέψαι νόον οὐδὲ παρελθεῖν.

Gossip is mischievous, light and easy to raise, but grievous to bear and hard to get rid of. No gossip ever dies away entirely, if many people voice it: it too is a kind of divinity.

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.’''
