Take two young men with the same talent. One is a good-looking kid from the Great Plains with a great voice. His five closest friends are his parents and classmates. The second kid is from London, Canada. His top five includes Usher, one of the biggest pop stars in the world, and Scooter Braun, one of the biggest talent managers in music. The first kid is a gifted nobody; the second kid is Justin Bieber. The difference isn’t the face or the falsetto. It’s the quality of the top five, the power of the network.
