1. Breaking it up during the day. I try to get about 400 words during my lunch break so I don't feel so overwhelmed when I get home.
2. Make bedtime sleep time. I make sure NaNoWriMo is not the last thing I do before going to bed. When my head hits the pillow, I don't want my mind to be racing with things I want to put on paper. So I watch a TV show, read a few pages or talk to a friend before hitting the sack.
3. Only enter in word count once a day. It's like the watched pot never boiling. When I'm worried about hitting my word count, it seems to take longer to get there.
4. Don't try to "make it up." If I fall behind in my word count, I can't spend the next day trying to make up for it. Some days the story comes a little easier for me and some days it doesn't. I just have to let it happen.
5. Turn off the internet! There is no greater time-suck than the World Wide Web. When I'm writing, I can't be checking e-mail, playing games on Facebook or mapping the fastest route to the nearest ice cream place.
So far so good. I'm still on track with my word count and having fun with it as well.
