Over halfway there...

I hit 20k words in my middle grade novel today.  It's very exciting to me, because I've never written anything this long before.  When I first started, I had an idea for the plot and an idea of the characters, but the thought of actually completing this book was overwhelming.  Little by little I've plugged away-it goes pretty slowly for me since I revise each chapter before I go on to the next.  In fact I revise each paragraph that way too.  Then I let my critique group rip it apart and I revise again based on their suggestions.  I check the word count constantly because I am still not confident about being able to write 25-30k words.  But I'm already at 20k, so I guess I can do another 10k.  Watch, I'll probably end up writing another 30k and have to cut, cut, cut.

So, what are you working on and where are you at in your project now?
