Everyone has negative times in their lives. Being negative isn't a bad thing. I think that shows how sensitive and rich your emotions are, and I think that because you've known sadness you can feel happy things more strongly than other people. But to be honest, it's tough to live life remaining negative all the time. So sometimes you should spend your time doing the things you love, saying goodbye to negativity, and living life happily. That's what this song is about.
