As for you, my galvanized friend, you want a heart. You don't know how lucky you are not to have one. Hearts will never be practical until they can be made unbreakable.
It doesn't matter if you have a heart or not. What does matter however is if you are willing to fight for what you believe in. Even then, when times are at their hardest, not only your mentality and emotions are unbreakable, but you yourself can't be hurt anymore.
