Latin Tattoo

I'm thinking about getting a phrase "what doesn't kill you, makes you stronger" on my back. I know that the original phrase was in german but I want to do it in Latin. Anyone out there who could help me translating this to latin. I tried online dictionaries and translators but I'm affraid of using them because latin is very complicated grammatically and I don't want to make a mistake that I'm going to be stuck with for the rest of my life... :) Thanks in advance!

Hi! The translation is "Quodlibet te non necat, fortium te facit". I'm pretty sure that's correct, I've been studying latin for 5 years now :) I hope that helped! Cheers, Francesca
