There are writers with a set schedule (they write from 8 am to noon, or whatever), but I'm not one of them. Life sets its own schedule! Maybe today my friend will need my help, or a cousin will show up unexpectedly from out of town; I have one class on Wed, another on Thurs, and I volunteer at the museum on Fri... On the other hand, I've tried setting word-count goals, and I find that's a great motivation. I can't stop today until I've written 3000 words-- even if I delete 2500 of them tomorrow.

I hope this helps. Thanks for joining the AMA.
