I'd like to talk about the mechanics of writing. I have a lovely large study with a very crowded desk on the second floor of my house. I write on a Mac, eventually editing on printed pages. My best days are when I wake up and immediately start to write. Write, write, write.
Many people plan to write, which is a farther cry than they realize from actually writing.
Try it first person, or third person. Reorganize the chapters. Change the characters. Put them in a new plot. Figure you haven't really written until at least the third revision.
