The song is a look at biographical milestones in the male narrator's life, focusing particularly on those occurring at the age of sixteen, eighteen, twenty-one and twenty-five.[1] In each verse, the narrator is at a certain point in his life, wishing to be slightly older.[2] Rhett said that he wrote the song when he was 25, and that it was one of the first he wrote for the Life Changes album. He also said that it was integral to the formation of the album, telling The Boot that "It was the first one that I really fell in love with. Then, I started to get in a room with [my co-writers for the album], and we really just started to shape Life Changes around all these different vibes, to make sure it was all really cohesive but every song still sounded fresh."[3]
