My new rhythm is this. 500 words a day. This takes shortly more than an hour. I can do it in one sitting or two, on days that I teach. I skipped yesterday because I did a zen retreat, but the idea is to have 6,000 words in 12 days.
I think I will need another 12 days to put all the references in, to perfect style and organization.
Needless to say, this only works if I already know the content of what I am writing. The amount of time I spent learning all the things I will be saying is incalculable.
I very much appreciate Edwin Denby's idea about dance writing. It involves two separate abilities: to observe what is happening, and to write. It is similar to Thomas's idea that you first know something, and then write it. As I work I also discover things that I do not know, so I have to do some additional research to answer ancillary questions.
