A good lot in life. Marcus Aurelius 5.36

Don't imagine that all is lost. Keep plugging away at good activities, finding ways to enjoy the processes they engage. The world is a spinning top (or in Greek, a rhombus).

Μὴ ὁλοσχερῶς τῇ φαντασίᾳ συναρπάζεσθαι, ἀλλὰ βοηθεῖν μὲν κατὰ δύναμιν καὶ κατ’ ἀξίαν, κἂν εἰς τὰ μέσα ἐλαττῶνται, μὴ μέντοι βλάβην αὐτὸ φαντάζεσθαι· κακὸν γὰρ ἔθος. ἀλλ’ ὡς ὁ γέρων ἀπελθὼν τὸν τοῦ θρεπτοῦ ῥόμβον ἀπῄτει, μεμνημένος ὅτι ῥόμβος, οὕτως οὖν καὶ ὧδε. ἐπεί τοι γίνῃ κλαίων ἐπὶ τῶν ἐμβόλων· ἄνθρωπε, ἐπελάθου τί ταῦτα ἦν; «ναί· ἀλλὰ τούτοις περισπούδαστα.» διὰ τοῦτ’ οὖν καὶ σὺ μωρὸς γένῃ; «Ἐγενόμην ποτέ, ὁπουδήποτε καταληφθείς, εὔμοιρος ἄνθρωπος.» τὸ δὲ εὔμοιρος, ἀγαθὴν μοῖραν σεαυτῷ ἀπονείμας· ἀγαθὴ δὲ μοῖρα· ἀγαθαὶ τροπαὶ ψυχῆς, ἀγαθαὶ ὁρμαί, ἀγαθαὶ πράξεις.

Never let imagination carry you away so completely from the moment that you cease to give others effective aid, according to your own real power and ability. Even if you find projects failing halfway through, don't imagine that all is lost, or ruined. That is bad behavior. Instead, be like the old man who kept asking his pupil for the latter's spinning top every time they parted, remembering its power. When its spinning began to rejoice him, folk would stare: “Dude, have you forgotten what this is?” “Sure,” he would respond, “but spins like these make a really excellent top!” “So you're turning into a fool, then?” they'd say, to which he'd reply, “As I understand it, I've become a lucky man.” This is luck: giving yourself a lot you deem good. A good lot includes a soul that handles changes well, yielding good impulses and good deeds.
