It is indeed a beautiful song. I am quite sure most people would listen to it and yet see it as an "Idealistic" song.
We live in strange times. A time where kindness is seeing as weakness and humility as a sign of stupidity. So instead of people trying to be inspired by those who are kind, they are the focus of ridicule.
Thank goodness, not everyone is like that and there are people who can understand that if we truly want to make a difference in the world, we need to start with ourselves. Cliche? Yes, but it is true. I refuse to let anyone tell me that I cannot make a difference.
