The world is your exercise book, the pages on which you do your sums. It is not reality, though you may express reality there if you wish. You are also free to write lies, or nonsense, or to tear the pages.
Richard BachThere are no mistakes. The events we bring upon ourselves, no matter how unpleasant, are necessary in order to learn what we need to learn; whatever steps we take, they're necessary to reach the places we've chosen to go.
Richard Bach
