Annotated Lyrics with Explanation

I think this song is about young girls that have low self esteem and look up to particular celebrities for inspiration. The artist herself had a rough childhood and she portrays this through her songs and through her lyrics. Therefore wanting to inspire many others that they shouldn't get down on themselves but instead look up, keep smiling and don't let other people get them down. The lyrics mention that it is okay to not fit in with the crowd, which is how she would like to see her fans feel about themselves.
