Are many people laboured with these beasts? I have a 13,000 word monster plus another one half its size due for May. I've written about a fifth of it, but don't really know what I'm doing! Just writing in quite an unstructured way and hoping it makes sense, it's a stressful business! I don't think I'd have even started if it wasn't for the genius of Write or Die, which tells you off if you get distracted from writing http://lab.drwicked.com/writeordie.html
Feel free to add stories of staring at computer screens/ reading for weeks and weeks/ deleting your own work by accident/ not having started anything yet below.
