For my my initial experiment into going off into a tangent, I thought the best way to start off with, is to photocopy the pages of my sketchbook (below) to then reform an identical booklet.
My theory was to then re-write all over the photocopied pages in the booklet made out of my sketchbook, so there is a second layer of my rambling.
I will then photocopy my edited booklet, and then re-write over the pages again...
I will continue this process twenty times. So in the end I will have twenty books which gradually build up more and more and more tangents. The writing will be written about whatever happens to be in my head at that moment. And so the final booklet will be extremely cluttered, illegible, and should be a good representation of what my head feels like something when I have so much going on at once.
