• The key melodic idea for this self-reflective ballad came to Mayer in a flash one December night in 2014. It hit him several months into the writing and recording of The Search For Everything at Capitol Records' Hollywood building.
  
  "I was sitting in that room," he told Rolling Stone, gesturing to one of the smaller enclaves adjacent to the main studio, "just off trying to find something. And out of nowhere, I start singing, 'I am not done changing, out on the run changing, I may be old and I may be young, but I am not done changing.' It's 30 seconds long and it was a jingle and I went, 'Oh s--t, how do I make this a song?,' because it was so rounded off and circular already. It sounds simple, but it took forever."
  
  Mayer added the song is "the spiritual centerpiece of the album."
