I think if we want to change the world we must change ourselfs, we are not perfect and i think we would never be but we can dream, we can try go foward we can attend to be good, if we try we will improve.
I think the problem in the world is that we just blame others we just dont look at yourself , all of us we all can be heroes with a kind heart and a good did to someoane wich we do not knew because what the point to do good to people we know?
