Going Challenge-Crazy

With the posting of my thoughts on Sheridan Le Fanu's Madam Crowl's Ghost and other stories, I have completed the RIP II Challenge. I do feel like I've achieved something with this. I wasn't certain when I signed up for various challenges if I would end up getting distracted by other things and not manage them, but the first one is done, hooray.
Completing this has given me perhaps a little too much confidence in my challenge completing abilities, as I have signed up for another, rather more demanding one; not reading this time but writing, NaNoWriMo.
This challenge (National Novel Writing Month) is to write a novel of at least fifty thousand words from scratch during November. My brother had a go at it last year and at the time I thought he must be a bit cracked in the head to even attempt it.

This year I have gone similarly mad, but am feeling very excited about it. I have had an idea for a story rattling around my head for the past couple of months, which has been very irritating as it has distracted me from the other things I'm trying to write. It is, if possible, even cheesier than the exorcist novel I'm halfway through, so I thought this challenge would be the perfect opportunity to get it out of my system in one quick burst and then get back to the ghost stories I prefer writing. If you want to check out my progress during November I have signed up as EloiseG - I was too late to be able to get Eloise.
The hardest part will be to avoid the temptation to edit. One of the hints of how to complete this mammoth task sent in the joining email was that editing is for December. I have a nasty habit of constantly going back over stories while I write them, which is probably why I have never managed to finish writing a novel. And that fact in itself says to me I might be being a bit ambitious in attempting this, but nothing ventured, nothing gained!
The first few chapters at least will be plain sailing as they are pretty well worked out in my head, and I have a good idea of what will happen at the end. So that's the first five and the last five thousand words sorted, and all I really have to worry about throughout November is the forty thousand words in between!

Oh dear, I think I am definitely a bit cracked in the head, it must be genetic.
