I just started trying to figure out how to write [something] which was unlike anything anybody had ever seen, and once I felt like I had figured that out I tried to figure out what kind of book I could write that would be unlike anything anybody had ever seen. When I started writing A Million Little Pieces I felt like it was the right story with the style I had been looking for, and I just kept going.
It's funny, because when you work on a set, everyone is watching you. You are being observed by everyone.
