Enchiridion, 2
ἄν τε γὰρ ὀρέγῃ τῶν οὐκ ἐφ᾽ ἡμῖν τινος, ἀτυχεῖν ἀνάγκη τῶν τε ἐφ᾽ ἡμῖν
“If you desire something [man] cannot control, it will certainly be your misfortune to not to have it.”
Enchiridion, 5
ταράσσει τοὺς ἀνθρώπους οὐ τὰ πράγματα, ἀλλὰ τὰ περὶ τῶν πραγμάτων δόγματα: οἷον ὁ θάνατος οὐδὲν δεινόν （ἐπεὶ καὶ Σωκράτει ἂν ἐφαίνετο）, ἀλλὰ τὸ δόγμα τὸ περὶ τοῦ θανάτου, διότι δεινόν, ἐκεῖνο τὸ δεινόν ἐστιν.
“Things themselves do not agitate people, but the appearance of things does. For example, death is nothing terrible (or at least it seemed so to Socrates), but the idea about death—that it is terrible—that is the thing of terror.”
Enchiridion 8
μὴ ζήτει τὰ γινόμενα γίνεσθαι ὡς θέλεις, ἀλλὰ θέλε τὰ γινόμενα ὡς γίνεται καὶ εὐροήσεις.
“Do not try to make events happen as you wish, but wish that they happen as they do and you will sail smoothly.”
Enchiridion 11
μηδέποτε ἐπὶ μηδενὸς εἴπῃς ὅτι ‘ἀπώλεσα αὐτό,’ ἀλλ᾽ ὅτι ‘ἀπέδωκα
“Never say of thing: I have lost it; but say instead: I have returned it.”
