I'm 17,500 words in, and suddenly realized that I hated one of my main character's names. I mean, really hated it. Not that it was a bad name, I just didn't like it for this character.
So, even though it's being read as I type (I post the day's progress in a locked journal post for a limited audience), I changed his name. And I like the one I chose.
I also did a nice jerking redirection of the scene's action, because I was BORED.
This is one of the greatest things I have learned from NaNoWRiMo. When things aren't working? CHANGE THEM. So what if it's a complete 360 from the previous paragraph. You can fix it when the first draft is done.
So, my story just got a wrenching change. And I feel motivated all of a sudden.
NOw, I've got less than three hours before Heroes, so I'd better get writing.
