Google has suggested words like fides, fiducia, spe, optimum and optimismus, but I want to make sure it goes together into a whole sentence. Thank you!
That can't really translate literally, but you could convey a similar idea, perhaps, with something like procurre confidens omnia bene cessura, "charge forward trusting that everything will go well/succeed".
Circling back on this old post because I might be *finally* ready for the tattoo - wondering if anyone else wanted to chime in on "Procurre confidens bene cessurum" being the best possible translation for the general feeling behind the quote "charge forward with trust and optimism"
