How to write a novel in 100 days or less

A friend of mine found this link How to write a novel in 100 days or less and I think the idea is very interesting . . . and tempting. I'm debating whether to try this out.

Of course it helps if you have a novel you're considering writing. So far I've given up on all the novels I've attempted. Even the ones that are still just ideas. You see I'm always thinking "that's not going to be novel length when you're done". Or "that idea has been done too many times before". Or the worst one of all "no one will care about this story besides you". That one's a whopper.

So I think I'll just shift into "Idea Generator" and see if there's something brewing on the back burners I forgot about. Or I'll just have to go out into the world and see if anything new sparks something in my mush of a brain.

Or, on the other hand I just might not do it.

That's me for ya. I get a lot of ideas but have trouble putting them into practice. Ideas I can come up with. Finished stories? Not so much. And with this tempting plan placed before me I also wonder if I should.

Why tackle a novel when I haven't mastered the short story yet? I know the two are not exactly the same when it comes to structure and such, but if I find it difficult to create a well rounded short story why torture myself with writing a novel? But then again I might be one of those writers who struggle with the short story but are really good at writing novels. If I don't write one how will I know? I guess there's only one way to find out.
