In this song, the title is the main topic at hand. Basically speaking on what 'one day' entitles, looking towards the future. Whether it's a desire or goal to accomplish, it's one that the speaker knows the person they're referring to needs to happen in order to feel free and to break away from current circumstance. It talks about barriers and taking it one day at a time, but the fear of never making it. However, there's a hopeful tone throughout the song as though the speaker is giving advice and has the confidence in them to instill hope that they will get there 'one day'.
