The Inevitable Writer's Block

If you're participating in NaNoWriMo this month, you should be about two thirds done with your novel.

If you're not, don't worry about it! And, either way, it seems like a good week to talk about writer's block.
Now, assuming that you've been writing this whole time, the most common forms of writer's block, namely not having an idea and not using the habit of writing to actually put words on the page, are not your problem. Maybe, you've gotten somewhere in the middle and your genius story seems to have stalled. Or, maybe you got to a blind alley and realized that your story took a wrong turn 1,500 words ago. It happens.
Either way, try to remember this is all about getting the words out and on paper. And, if that's not enough to get you going again, head over to Gizmodo and check out their advice on The 10 Types of Writer's Block and How To Overcome Them. Not all of it will apply, obviously, but I'd lay odds that at least one of those ten types of writer's block will at least come close to applying to you. Naturally, I think the advice will help, too. And, in fact, I encourage you to read all the advice, because something that doesn't seem like it applies to your frustration may end up being what knocks you loose and starts you writing again.

Another helpful resource that can help you get through a block is your fellow NaNoWriMo writers. You can connect with hundreds of people who are also participating in NaNoWriMo in the NaNoWriMo Forums. The people there can be incredibly supportive and helpful and they may need a break from their writing at this point, too.

Again, the most important thing is to get your rough draft out this month. After you get the thing written, you can take a break and come back to edit it into shape. Don't worry about that now. Just worry about getting your first draft written.
So, go, read as much as you need to to get past your block, then get back to writing!
