Yesterday I got two and a half hours to write and I managed to write a whole chapter. Over 2500 words done. I'm feeling pretty awesome about that.
Writing from a handwritten outline is working well for me. I'm wondering if part of the trouble I had before was that I had to switch screens on my computer to go back and forth between the outline and the text I was writing. Now I just have to glance off to the side.
I've also put together character sheets for my main characters with a photo and basic notes about description. But I'm also using those sheets to inscribe notes such as behaviour tics (tapping fingers while nervous) or if I want to use a theme to describe a particular character (snake metaphors, cat metaphors, etc). I'm hoping it will keep my writing consistent and save me some work in rewrites.
If I can keep going at this pace and keep committed to my writing days, I have a real chance at getting this manuscript done before my six month target.
