After checking several online databases/dictionaries, I have been unable to find a source for what I assumed was a familiar Latin idiom, Cave quid optes. Could it be apocryphal? In an essay I'm writing I attribute the phrase very generally to Romans, but I would like to name an author like Horace or Ovid, if possible. Anyone know why I can't find a single entry for this? Is my spelling incorrect?
Thanks for any advice.
