I try not to dwell on the past. I'm not a big go-back-and-try-to-relive-your-past kinda person.
I always liked it when people go back in time to discover things about themselves, like with 'A Christmas Carol' and you're getting a tour of your life by the ghosts of Christmas past, present and future.
People try to keep their past, like kind of holding on to their past. Every Springsteen song talks about that.
