This song concerns limiting ambition to stave off failure. Barnett explained to Uncut magazine: "I think that's a natural defence mechanism, but then you also don't get anywhere (I'm projecting). So I started challenging myself to do something. My ambition stems from my will to achieve something to keep me from going insane."
