R&B singer Usher wants Justin Bieber to enjoy his success and appreciate everything he gets to experience. The Scream hitmaker, who co-manages the teenage heartthrob and has helped Bieber to become a pop sensation, said the 18-year-old singer should not worry about things which are out of his control, reported Contactmusic. "I see him and his crazy life and just tell him to enjoy it. When I started out, things were crazy so I say to Justin, Life is not worth it if you're not living it. Creative people are perfectionists and obsess over things. Sometimes we need to relax and have fun. "So Justin, enjoy it as I went round the world three times before I decided to look up and see it. Absorbing your surroundings when you travel is so important," he said.
