That's some sad stuff.  Except the best part of the word?  The COURAGE part.  Never let go of it.  You cannot let go of your courage and your hope.  Even if you're the last person on earth who believes in you, you must always hold your head up, continue to hope for something better, and have the courage to keep on going.
