I think sometimes all you need is to hear someone else say the same thing that you're going through to realize that you're not alone. I try to put some sense of hope into the songs into whatever the situation is so that it's not just dirt drudgery and a life of misery.
I didn't fully realize it at the time but the goal of my life was profoundly molded by this experience - to help produce in the next generation more Mother Teresas and less Hitlers.
