There is no greatness where there is not simplicity, goodness, and truth."War and Peace"
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 every one 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 but there will be no special hurry."A Farewell to Arms"
Do not be too moral. You may cheat yourself out of much life. Aim above morality. Be not simply good; be good for something.
