I believe that what Mariah Carey is trying to get across is very inspiring and helps people to believe in themselves. If you feel like no one is there for you I think this song shows you that you’re a hero and that you can do it all by yourself. I think the lyrics mean that everyone is a hero. Like sometimes when I have to do things on my own and no one is there, I am my own hero and help myself through my problems by guiding myself to where I think I will succeed. Almost like when I take a test in school. Sometimes you need to be a hero to help yourself out. Other times you need to be a hero to help others out. Either way a hero is inspiring to people and everyone is a hero.
