Sia wrote this self-help ballad at her small apartment in the Angelino Heights neighborhood of Los Angeles. She originally sent the song to her friend Katy Perry's computer, but the "Roar
" singer didn't see the email. The Australian songwriter then passed the song onto Rihanna's manager, who held it for eight months without doing anything with it. Once Beyoncé got hold of the tune she immediately wanted it for herself. When Perry heard her recording, she asked her pal why she hadn't had first dibs on the song. Sia responded by saying, "Check your email."
