This was the hardest song to write for the movie. The Lopezes knew it was about the end of Elsa's journey, but were unsure at the time how she got there. Their first draft had the same chorus but a different feel. Once they watched the first round of visuals with "Show Yourself," they knew the middle and ending had to be changed. Anderson-Lopez recalled to Billboard
"It went back and forth for months - it's now four minutes and 20 seconds and it has a big ending. It transformed a lot, and it was hard."
