hey starlight, I like your quote, it's one of my favorite !
Hmm, as for me i bet everyone knows this one : "Ce qui ne te tue pas te rend plus fort", which in english gives something like "what does not kill you makes you stronger". I looked for an official traduction but I can't seem to find one. I think there is something more appropriate.
Anyway the reason for this being one of my favorite is that when we get hurt and depressed, thinking about this helps me to move forward and start everything over. Finding the energy to stand up and fight back at the thing we call "Life" may be hard sometimes.
