It's November, which mean that it is also National Novel Writing Month! Also known as NaNoWriMo, its goal is to encourage you (and everyone else) to abandon their excuses and write 50,000 words of a novel. Start today, write fewer than 1700 words every day, and you will be done with your first draft. Find more at their site, including community, tips on word counting, stories of successes, tales of standard problems and solutions, and so on.
Or, just write. Write. And after that, write some more, until you have 50,000 words or more.
