I just finished an online writing course. When it comes to the dialog that you said slows you down. One of the pros in this class apparently set her computer to center and plugged it out quickly. None of that other stuff was written down in the rough, rough draft--such as what did who say and how they said it and all that stuff that slows you down.
I have a memory problem when my head is going 100 times faster than my fingers can go. The trick really worked wonders for me and kept me moving at a faster rate of speed. Once down, then you can always go back and get it into normal novel format. So it looks sort of like this:
Okay forget the example, blasted centering tool isn't working. But you can get my drift. Name in center, next line the action centered, then the dialog.... Sort of like script writing I guess. Really fast, really easy & keeps you moving forward.
None of the others in the class thought it helpful, but my Pooh size brain really did! Did some nice work today on my piece, both in planning in my head and getting a lot of it into word doc.
Best wishes as you go forward! Meg
