Hard to find a good and short Latin proverb for the same purpose, especially since some sources are positively loquacious
Compare:
Ne quid nimis - Not too much of anything. [Terentius]
with:
Nolite thesaurizare vobis thesauros in terra - Don't gather earthly treasures [Matthew]
But there's also:
Sic transit gloria mundi - Thus passes worldly glories (while setting a ritual fire to celebrate the election of a pope, implication here also being that worldly desires are now left behind to leave room only for the highest purposes) [Patricius]
