So, this is the sentence:
Faustus’s annihilation is a sobering reminder of our own human shortcomings; the parable resonates throughout the ages, encouraging even us, as a modern audience, to re-evaluate the things that we are using to make ourselves happy.
And what I'm not happy with is the final phrase, in particular the word 'things', which sounds a bit too sloppy...
Any ideas? Thanks in advance!
