It is for you to arrange your priorities; but whatever you decide to do, don’t do it resentfully, as if you were being imposed on. - Epictetus

Μηδαμοῦ σεαυτὸν εἴπῃς φιλόσοφον μηδὲ λάλει τὸ πολὺ ἐν ἰδιώταις περὶ τῶν θεωρημάτων, ἀλλὰ ποίει τὸ ἀπὸ τῶν θεωρημάτων· οἷον ἐν συμποσίῳ μὴ λέγε, πῶς δεῖ ἐσθίειν, ἀλλ' ἔσθιε, ὡς δεῖ.

Enchiridion 46, the handbook of Epictetus's teaching compiled by his student Arrian.

To admonish is better than to reproach for admonition is mild and friendly, but reproach is harsh and insulting; and admonition corrects those who are doing wrong, but reproach only convicts them.

Ὅταν ἅπτεσθαί τινος ἔργου μέλλῃς, ὑπομίμνῃσκε σεαυτόν, ὁποῖόν ἐστι τὸ ἔργον. ἐὰν λουσόμενος ἀπίῃς, πρόβαλλε σεαυτῷ τὰ γινόμενα ἐν βαλανείῳ, τοὺς ἀποῤῥαίνοντας, τοὺς ἐγκρουομένους, τοὺς λοιδοροῦντας, τοὺς κλέπτοντας.
