I'm grateful not to have suffered from it in any sustained way--I think journalism beats that out of you--but of course, I've had days on which I've felt either that I didn't know how to get my ideas out of my head and onto the page or that the sentences just wouldn't come. So sometimes I walk away, just to think, because if I'm stuck, there's almost always an underlying problem with the idea itself. And sometimes I'll just start writing anyway--writing garbage that I know I won't submit but that will help me figure out why I'm having trouble.
With Dramatica I find I never run into writer's block. In fact I usually end up with too many things to write rather than struggle with not enough. And I think most of that has to do with the fact that the "underlying problem" Harris speaks of is exactly the kind of thing Dramatica pinpoints. The whole thing is kind of a problem-engine that makes sure all the parts work together in harmony.
