1. Even though I end each day thinking that I'm all writ out and these 2,000 words are the last I'll ever write, somehow the next day I wind up writing 2,000 more.
2. The parts that I have the most fun writing are the parts that require the least editing the next day. Yes, I know you're not supposed to edit during NaNoWriMo and I haven't really edited, meaning I haven't done a read-through of what I've written since November 1 (see counter above!), but I do start off each morning by going over what I wrote the day before to give me a springboard for the new day. And I quickly saw that the skydiving parts are a lot more fun to write and a lot better than the non-skydiving parts (you can see a video of my recent jump, if you're interested).
4. If I take a day off, it's hard to get back in the groove the next day. Hmmm. Maybe, despite all my protestations, there's some truth to this "write every day" thing.
5. Writing full-time is hard.
