*"Soon you'll be ashes, or bones. A mere name at most - and even that is just a sound, an echo. The things we want in life are empty, stale, and trivial. So treat human beings as they deserve, be tolerant with others and strict with yourself. Remember, nothing belongs to you but your flesh and blood - and nothing else is under your control" - Marcus Aurelius
