I endlessly enjoyed the comparison with a Turning Machine. When I study someone's complex work, I do notes to keep several things in my sight scope: a piece of paper, PowerPoint slide or some fancy markdown text editor with syntax highlight. Seems like that this focusing is somewhat the natural way of building neuronal connections: if a logical piece is missing we have to use imagination to complete it and only then it nicely fits into our brain's "hologram" of the world.

There is a wonderful book "Exploring Writing" by John Langan. I found it in our library when I was in my PhD writing phase. I highly recommend it to anyone who has problems building text and who wants to learn how to master its structuring.
