Mattissimo, how would you improve the translation? Could you justify your vote, please?

Mente quieta nao é mente serena

I have to admit that I am not sure what would be the best Latin translation for the English phrase "Everything is a matter of..."...
The meaning is close to: "Everything depends on...". Am I right?

If so, how about "Omnia ex animo aequo, spina erecta et corde quieto pendent", dear?

animus serenus --> animus quietus/aequus?

Your suggestion is very good, but in this way we miss "to keep" which is, in my opinion, quite important. You know, it's something like: Everything depends on the fact that you always keep mind quiet etc., even in difficulties.

Ah, I like animus aequus very much.

You're right, Efee. My proposition doesn't quite convey the source. Ok, let's leave your version, dear. I will only replace "serenum" with "aequum" since you like it.
