Visual ways to sort out how to write your book, plan it, use the plan to write faster, know what to do once it is written to get it publish and bought by readers.
I write because I like to do something creative that also uses my mind. My posts are work I have done towards what I hope will be published book/s. I lead a writing group that wanted to learn more about all sorts of writing topics. We found using a Mindmap gave them a big picture and they could add their own observations on the back for the smaller picture. It was easy to understand and gave them focus.
