"Co nie zabije to wzmocni?" - correct me if I'm wrong

Is this how poles would say, "what doesn't kill you makes you stronger" ?

Co nie zabije to wzmocni

co cię nie zabije to cię wzmocni....

Is that how any pole would say that? In their context of language? I'm not sure how english translates to polish...

yes...

I corroborate. I say it to my students when they get an F. :):):):)

haha nice and thanks for the feedback

oh really? that's nice...
my physics professor used to say to the F students: "life is a b!tch"...
:)

Nietszche, of Polish origins by the way, first coined this phrase, I think:

"Was mich nicht umbringt, macht mich staerker."

and in Latin here:
Quod te non occidit, te certe fortiorem reddere poterit...- That which does not kill will only serve to make you stronger
(*....i like it...*)
:)

I like that. But how do you pronounce the polish version of this saying?

you can't.. it's hard for a non speaker

tso tsye nye zabeeyeh to tsye wsmotsnee

you have always al least 2 options:
1). to be desperated and fail in some departments or:
2). to fight and try to deal with sth what is difficult for you
so: if you get up not beaten by problems, you can say then you became stronger
