mamabebe - That is good advice. That's what everyone recommends in the Nano forums, which get pretty busy the closer to Nov it gets. Deleting just wastes time. Most people recommend that you don't do any edits. I barely even reread as I went last year. Sometimes I would reread the previous days work just to get myself back into the flow.
I think they actually have a planned month to do edits - March, perhaps. I'm not sure as I didn't do it. I think I'm shelving last years novel permanently. It was my first novel, so I was getting a feel for it and it would need too much work. This year, I've got a better idea of what I'm doing. I've got my idea and will try to figure out who the main character and supporting characters are ahead of time.
It is doable. I think anyone can do it. It's just a matter of pacing yourself, not letting yourself skip too many days of writing and not comparing yourself to anyone else. It can get discouraging to see people who have completed it in the first week!
But, I had a system that worked for me last year. I would do my writing for the day, then jot out a quick outline for the next days writing. I generally started a new chapter each day, so I would write down who was in the next scene, what their goal for that scene was, how I wanted it to end and a few other details. This gave me an excellent starting point for the next day and made it so much easier to sit down and type.
Completing it last year was such a rush - it seriously is right up there with the big moments in my life - childbirth, marriage, graduations and finishing Nanowrimo!
I am EXCITED to do it again!
