Превод - Португалски Бразилски-Латински - Aproveite tudo, a vida é muito curta para...

Hello Alex!

I don't know Portuguese, but would make some changes. Tell me, if you disagree, ok?

"vita brevissima est ut paeniteat" --> vita nimium brevis est ut paeniteas*

*If you turn to 2nd person, you should keep the person in a dependent clause too.

Hello again Aneta!

Mh it's very interesting and useful that "nimius". I didn't know its existence.
Sometimes I ask myself if I'm too young and inexperienced to play at being a Latin translator
About "paeniteas", the Portuguese corresponding verb is "arrepender-se", that implies a subject as the English impersonal "you".
It's a generic subject, I don't know if in the Slavic Languages exists something similar.
Then, I studied that "miseret, paenitet, piget, pudet, taedet" are "verbi assolutamente impersonali", with no subject except the 3rd singular person.
Is it true at all?

Oh, no! You are not too young to translate into Latin! You know everybody has his/her beginnings... And you present a very good level although the age.

Yes, this is truth: the verbs function as impersonal in 3rd person, but they function also as normal verbs in other persons. And I believe it is just the case in your sentence.

Do I guess well? You meant: Life is too short to regret. ??
If so, "regret" makes reference to to the second person, because you typed before "Omnibus rebus utere" - Use/enjoy all things (imperative in second person).

Oh well. Then you're right.
"Paeniteat" becomes "paeniteas" and the phrases get also more consistent.
I'll change my translation now.
Thanks for all your teachings, Aneta!

My pleasure! I love my job...
Let's see what the poll says now.

Don't you mind giving me one more, dear Lizzz?
