This song "Firework" by Katy Perry is beautiful. speak about life, about how we should face it with courage first of all, teaches us that in us there is a light, a firework that could fly only if we believe in ourselves. My favorite lines of the song are the same for all these years, for example: “You don't have to feel like a waste of space, you're original, cannot be replaced” and "Maybe you're reason why all the doors are closed. So you could open one that leads you to the perfect road". Observe the little stories related on video.
