Every year, thousands of writers from around the world participate in National Novel Writing Month. The goal is 50,000 words in 30 days. There are forums on the site where writers keep each other encouraged, motivated, and help brainstorm and share ideas to help fellow writers create the best work of fiction possible.
I participate every year. I've only gotten to 50,000 words once or twice. The other times, it was still worthwhile. I get a whole lot of writing done in a short period of time.
