I'm really anxious about a lot of things (lack of dissertation topic, conference paper to write, bad teaching last week), but here are some bits of gnomic wisdom from Pindar:
εἰ δέ τις ὄλβον ἔχων μορφᾷ παραμεύσεται ἄλλους,
ἔν τ᾽ ἀέθλοισιν ἀριστεύων ἐπέδειξεν βίαν,
θνατὰ μεμνάσθω περιστέλλων μέλη,
καὶ τελευτὰν ἁπάντων γᾶν ἐπιεσσόμενος:
If someone has wealth and outpaces everyone else in beauty, and showed his strength by excelling in competitions, let him remember that he decks out mortal limbs and will put on everyone's last garment of earth.
ἐν σχερῷ δ᾽ οὔτ᾽ ὦν μέλαιναι καρπὸν ἔδωκαν ἄρουραι,
δένδρεά τ᾽ οὐκ ἐθέλει πάσαις ἐτέων περόδοις
ἄνθος εὐῶδες φέρειν πλούτῳ ἴσον,
ἀλλ᾽ ἐν ἀμείβοντι. καὶ θνατὸν οὕτως ἔθνος ἄγει
μοῖρα. τὸ δ᾽ ἐκ Διὸς ἀνθρώποις σαφὲς οὐχ ἕπεται
τέκμαρ: ἀλλ᾽ ἔμπαν μεγαλανορίαις ἐμβαίνομεν,
ἔργα τε πολλὰ μενοινῶντες: δέδεται γὰρ ἀναιδεῖ
ἐλπίδι γυῖα: προμαθείας δ᾽ ἀπόκεινται ῥοαί.
κερδέων δὲ χρὴ μέτρον θηρευέμεν:
ἀπροσίκτων δ᾽ ἐρώτων ὀξύτεραι μανίαι.
Since, you know, black fields don't give fruit in a row, and branches don't tend to bear at all the turns of the years a fragrant flower that is equally rich; but they alternate. Fate leads the mortal race, too, this way, and clear signs do not come from Zeus to humankind. But all the same we embark on proud ambitions, eager to do many deeds. For our limbs are fettered to unrestrainable hope, and Foreknowledge's streams are not nearby. But one must hunt out moderation in gain; and unattainable passions come with bitterer obsession.
