that's a tricky one.
Because my writing for the last 20 years has been so technical, I write in an order. First, I have to research, find the articles I need, read them, process that, cross-reference it in my mind with a whole lot of other stuff, and then there comes a point where a light switches on.
At that point, then I write. There is no point in writing before that because it will not flow.
Up until two months ago, my best writing was done in the 10 days before my period came, but having been thrown into menopause, I'm going to have to chill until I can work out how my body/brain connection will work out.
At the moment, I'm just working at night, when its quietest and there are no distractions, because I'm working on the final edit of a book, which then goes back to the publisher for proof reading and all that stuff.
While they do graphics and stuff, I'll probably start working on the next one. But again, it will be stuff I can't just sit and allocate X hours a day or whatever.
Even with embroidery (Traditional japanese embroidery), I embroider when the brain clicks in, and I understand the feel of the piece. If I try to embroider because it should be done, then I loose the feel and it becomes a technical mechanical exercise, and I don't relate to it. Writing is also like that with me.
