There's YT channel dedicated to materials about music industry and souled musicians.

Bob Dylan apparently became great in a very short period of time from being complete noob and he achieved that by sacrifice made on the crossroads. He doesn't even really keep that as a secret.

Worth checking out for those interested.

From Queen, Dylan, Beatles to Lady Gaga, Katy Perry and others.
