Well, its been 4 days since I started, like everyone else. I've only reached about 2000 words but its shaping up pretty damn nicely. I'm told by people that I specfically told not to bullshit me (I want honest input, not positive) that it is very powerful and vivid and they can't wait to read the next chapter.
I don't think I'll be making 50,000 within the month, but I think I'll reach 90,000 within 3 months and it'll be something I'm proud of, not rushed.
Nano was really just a reason to start a novel, it made me think about it and gave me inspiration one night when I was walking down a dimly lit street. That should give you an idea of the atmosphere in my novel.
