It is much harder to write a story in which you have a deep emotional investment. I have spent a year working on Evelyn's story, but going into NaNo, I'm left with no character names, no town names, and many many plotholes. The truth is that my story is still a series of ideas without much holding them together, and I don't want to rush through this. I know that the story is good, and I want to do it justice and give it the time and love it needs. Besides, I'm already stumped at 900 words.
I'm starting over with a new story--an account of the last few months of my life, and how my life has become so intwined with that of a complete stranger. Because really that's all I can think about right now.
