It means hold on to whats right, and stick to your guns, even when everyone else has given in to the succession of lesser men. Be the man you were meant to be while you still have the chance. A song that really ties into the movie in a way that's just so brilliant that you can't overlook the connection. Walt took a stand in the movie for what's right, and while there are plenty of people in the world who will never see life through his eyes or Thao's, we all have our own times when we have to do whats right. A beautiful song for a beautiful film that deserves every praise you can throw at it.
