Justin Bieber penned this Purpose track with regular collaborator Jason "Poo Bear" Boyd and Mark "The Mogul" Jackson (Trey Songz's "Please Return My Calls"). He first teased the tune back in March 2014, but kept the song in the vault for some time before recording it for the album.
Bieber said at an album launch event that the track means a lot to him. "'Life Is Worth Living' for me was just... I wanted to once again just share my journey," he explained. "Share the fact that there are people that are stressed out, people that are going through problems. I think when you're being the best version of yourself, you surround yourself with people that are encouraging."
