Nature has given to each conscious being every power she possesses, and one of these abilities is this: just as Nature converts and alters every obstacle and opposition, and fits them into their predestined place, making them a part of herself, so too the rational person is able to finesse every obstacle into an opportunity, and to use it for whatever purpose it may suit.
