Found something else to help me stay motivated: split my writing time up into 30-minute tasks.  Even if I'm absolutely unmotivated and do not want to work on something, I can manage to do it for 30 minutes.  So, I spend 30 minutes on outlining the next scenes in my novel, then 30 minutes writing my rough draft.  Other tasks include writing in my Writing Practice Notebook and editing.  Even if I'm not in a writing mood, I can at least manage 30 minutes on my most important or pressing project.  And since I'm usually juggling several different projects, this works out well.  I've been doing much better on deadlines and I'm making more progress on my novel than I have for a long time.
