Using firework as something to describe one's abilities and traits is one great symbolization. It lets us believe in ourselves - that all of us are unique and we have a particular reason here in earth. We justy sometimes need to search within ourselves to find out our deeper sense of being.
Like Katy Perry said, we should let our colors burst and make others recognize. We are different in our respecive ways and we should be porud of who we are. Katy Perry really made me love her more. This song is a wonderful piece that makes a message across.
