You've got to get obsessed and stay obsessed

With anything, I think it's the skill of the author as to how any POV works out. I'm a big believer in the story writing itself, and showing the author how it should be written. I remember writing a short story in first person and submitting it to a publisher, who said she would prefer it in third person. I rewrote it in third person, and it just didn't have any lift at all. It was functional, but it had lost its spark. I ended up not resubmitting it because it was not the story I had written.
