Write and Edit are two really different processes. Both are exhausting, but really different. With the years and the books I had created I had learn the process of creation and edition not only required different eyes, but different platforms.
In my case I write using Byword on the iPad. I like to write in black background with white font. When I edit, I also use the iPad but I do it on Plain Text, using white background and black font. I could do that on Byword but I like that using Plain Text I don’t need to change how one or the other is configured.
My brain associate the black background with creation, freedom, not worry bout mistakes or things. Instead on a white background, my mind gets more critical, looking for errors and more that I am doing.
The simple difference of the color on the screen allow me to have two different places to work. The difference may be simple, but it is powerful.
