Is it feasible, I wanna know now? (Bob Marley)

I was listening to Bob Marley's "Waiting in Vain" while doing the readings by Barron and Harper and enjoyed the way they gave real examples and information regarding revision. The one gripe i had was that all the students were writing about real-life experiences that they had lived. But would these exercises work with creative, non-fiction, or poetry writing? I think students are more hesitant to share creative writings as openly as they do writing non-fiction. Also, Barron didn't mention the valuable class time it takes to allocate time to students for typing and for individual teacher-student conferences for revision. For these reasons, I wanted to ask "Is it feasible?"
