I confess (knock on wood) that I rarely get it. But I'm very aware of not force writing. I've sat down at the keyboard and done this before and then the quality of the writing on review is poor. I have a number of projects on the go, so if I'm stuck, I'll move from one to the other. I'll also think about the next steps when I'm out jogging or driving. Hope that helps anyone who is stuck on the page!
