Umseting - Franskt-Enskt - bonjour. ce boulot, c'est la chance de ma vie,...

Can someone please explain "j'y crois à mort!"? "I believe in it blindly" is not an expression I've ever heard of in English.

Well, "to believe in sth blindly" means to believe in something without questionning it, but then it also has a pretty strong negative connotation, as it pretty much means the person in question has no critical approach at all. I've never heard someone say that out about his/her own belief, as it usually means the belief is in fact unfounded. This explains why I decided to consider it as not quite right.

"a mort" ( literally "to death" ) basically just means "a great lot". Since it's an informal expression, I personally would have translated it to "I totally believe in it" or (a little less idiomatic) "I really believe in it".

Thank you Coco, I edited it with "totally". Actually, I didn't know that "to believe blindly"
had only a negative meaning in English. In Italian "credere ciecamente" may be also positive, when it means to have complete confidence in someone/thing

Now that it is edited this way, I think that this translation is good and can be validated

No problem, Apple
