Ok, dear Ernst. Thank you so much.
I'm sorry Efee. I just had to be sure. This is why I asked Ernst.
Some questions to you:
"Minime tibi dicendum sit numquam".
and
"Tibi vivendum sit donec vivis".
Why did you use coniunctivi here? Shouldn't be "est" instead of "sit"?
And since the folowing sentence doesn't contain a verb "should" (like the ones above) but "have to", I would suggest:
"Si A dixisti, tibi dicendum est B".
--> Si A dixisti, tibi dicere B necesse est.
just to diistinguish between the sentences above and this one.
The rest is just great!
