Seek until there is no hope and then seek further. Seek without end. Trudge on without tiring and without fear and without disheartenment. Trudge on, for it is within you to fight any enemy. It is who you are. It is your past and your present and your future. You will not quit. You cannot quit. Your breath is your courage, and as you breathe, so must you hope or you are already dead.
