Heller wrote this song with Jim McGorman, whose clients include Avril Lavigne and Cassadee Pope. She spent much of her senior year of high school working with a less experienced producer in a local studio, which forced her to learn more about how to create a song. By the time she hooked up with McGorman, she had more confidence and was happy to share her ideas.
In her Songfacts interview
, Heller talked about writing the song. "I had grown a lot as a singer-songwriter so when we sat down to write my new EP of songs we started writing 'Hope.' We came up with some chords on the piano. This is how I write most of my songs. Some have a little variation, but once we find a chord progression we really like I usually hum along to find a melody and then we put words to it.
So, when we got that hook, the main line was:Hope, hope for the best
Hope for the rest of our life
Till the day that we die
We got that surprisingly super quickly. Most songs take us up to an hour to just find one good line which might just be in a verse, but we got the main line of the song in like five minutes. And after that, it was just amazing. We were building on each other's ideas. We built the whole chorus in less than half an hour, and then the verses were just super easy. We just went through different experiences of my life and what I wanted to say with this song."
