If people bring so much courage to this world the world has to kill them to break them, so of course it kills them. The world breaks everyone and afterward many are strong at the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too ut there will be no special hurry. Ernest Hemingway. A Farewell to Arms

Especially -- The world breaks everyone and afterward many are strong at the broken places... Such a true thing, many are not stronger, just more or less broken. It's such a corrective to that nonsense that "what doesn't kill you makes you stronger."
