Authors have been seeking ways to avoid distractions for decades, and it goes well beyond pervasive connectivity. Sometimes the very features that aid them in their work can also hinder them. For example: computers vastly simplify the editing process, yet one of the earliest pieces of advice I saw was to turn off the computer monitor while writing in order to avoid editing prematurely.

I do this by closing my eyes while writing. Makes the writing more descriptive and easier to imagine big scenes with a lot of color and vibrance. Using the 10 finger writing system, I am really fast doing this.
