I’ve done National Novel Writing Month (NaNoWriMo) for the past eight years. It is a frantic month as I write 50,000 words in a single month. At the end of the month, I am worn out, and I have a partially finished book.
The folks that run NaNo have done summer camps, where you get to set the pace, and work on what you want. You get put in a cabin of people who are supposed to cheer you on and interact. I get care packages (advice from published writers) and activities (such as virtual write-ins)
This year I am doing Camp NaNo. I have been put in a cabin, which seems full of introverts. But I am working on a book, the same book from two years ago. And it feels good.
