Proverbs 27 - 29

Life is uncertain.  The wise person prepares for life based on principles that do not change.  A fool changes his mind and his decisions based on emotions that are never permanent.  The fool ignores warning signs to his own detriment.  The wise seeks to learn from every situation, even if not personally involved in the situation.  Life makes no sense to the fool, as they have no anchoring point for their world view.
