la troppa bonezza

La troppa bonezza finisce nella monnezza.

Nice guys finish last. (Literally, too much goodness ends up in the trash.)

Grammatically this one's a good reminder of the -isc verbs, the subset of -ire verbs that have an -isc- inserted between the stem and the ending of the io, tu, lui/lei and loro forms.

finire

io finisco
tu finisci
lui / lei finisce
noi finiamo
voi finite
loro finiscono
