I think this song is about not having any regrets about things you did or had (a relationship) in your past and just letting things happen because they have to happen. He seems to be talking about things that happened in his past, but having no regrets about them yet he is wondering what will happen in the future.
I also think this song has a positive message, saying "do not care what others think about you, nobody knows you and nobody gives a damn"
