If you're taking part in NaNoWriMo you should be hitting 10,000 today. If you already have, then congrats! I've just hit 10,500 myself and it's still early here in England.
I'm getting tough on the site though. If you're on my buddy list and you're still dragging under 2,000 words then prepare to be cut off the list! Harsh, I know. In half an hours time I'm going to be purging those people off the list.
It's angled more to be an incentive for you to keep writing. Keep up the pace. Don't fall behind. This month is a long, sprinting marathon; not an easy country jog.
If you're struggling, one thing that stopped me from reaching the 50,000 marks in years before is that I was editing too much. I was re-reading and re-writing. It is so difficult not to do. Just try your hardest to avoid this. Don't pause for spelling mistakes or grammar errors, focus on the next word not the last.
I also have learned to keep track of what I've written; jotting down quick and important notes that have happened so far. It means I don't have to go scrolling back through the mess to locate important information.
List 'em off here; what's your word count so far? Have you had any unexpected surprises? Do you wish you'd done another genre? Vent it all here.
