This song was written by Diamandis during a trip to Los Angeles, a week after The Family Jewels
was mastered. The Greek-Welsh singer explained in press materials that the song encompasses all of her fears and aspirations for the future. "The song was written in response to be terrified of not achieving what I say I want to achieve every time I open my big mouth. It's my part ii to 'Mowgli's Road
.' I was paralyzed by fear before my trip to the States and couldn't stop thinking about being a failure and was convinced that I'd become a self-fulfilling prophecy if my brain didn't shut up and stop being so negative. So I put it in a song. Mowgli's questioned who I want to be, 'Oh No!' confirms it. It made me feel confident again after a shaky 6 months. Life is just a barrel of laughs at end of day, anyway!"
