 "'It is my bad luck that this has happened to me.'  No, you should rather say: 'It is my good luck that, although this has happened to me, I can bear it without pain, neither crushed by the present, nor fearful of the future.'  Because such a thing could have happened to any man, but not every man could have borne it." - Marcus Aurelius
