Dwayne "The Rock" Johnson says he owes his ENTIRE career to a traumatic experience from his childhood -- a traumatic experience that inspired him to spend every waking hour in the gym.
The confessional was shot for a documentary which chronicled the build up to the Rock's upcoming match against John Cena at Wrestlemania XXVIII this weekend.
During an emotional car ride, Rock opens up about the time he and his family were evicted from their apartment in Hawaii when he was 14 years old.
Rock says he'll never forget the look of despair on his mom's face when she tried to explain why he couldn't sleep in his own bed that night.
As a result, Rock says he resolved to change his life forever ... so he'd never experience anything like that ever again -- and the change began in the weightroom.
