Have you heard of NaNoWriMo? The goal is to write, specificially a novel. You are to write until you hit 50,000 words or December 1st, whichever comes first.
I have no delusions that I could do this. Right now I am hard pressed to write a letter, and fiction writing is tough because you have that tricky dialouge thing going on. But on the off chance someone who reads my blog may have an interest in writing, this may be the one thing that spurs you on. I'm thinking it would be an excellent project for ones who are homeschooling teens.
So you have a burning desire to write this may be just the thing that you need to spur you on. And if you do write a novel, let me know.
