I think so, too. I know I felt that way. For years. It was as if I was a character in a movie and the real action was about to start at any minute. But I think some people wait forever, and only at the end of their lives do they realize that their life has happened while they were waiting for it to start.
You take something from your past that you're somewhat ashamed about and you write about it from another character's point of view.
