I run three things, notes to outline to story, and then simultaneously afterward. It actually feels more flexible that way and easier to keep track of changes. It’s so much easier now than before the computer.
Oh, I can remember women in a writers club that I belonged to would fret about sitting in front of a blank page on a computer. Now that probably cannot write with out it.
I rely so heavily on Word to write and store docs. So glad I have the ease of the 21 Century at my finger tips.
