what doesnt kill you makes you stronger

What doesnt kill you makes you stronger, which is actually a quite inaccurate concept, is the idea that when you go through something very terrible but survive this thing, that it will make you a stronger person. The meaning behind it is one which comes with two different circumstances; the first is the negative effect of this horrid event which might make you lose part of yourself through the ordeal, and the second is more positive where you might learn from it.
