In an earlier post, I wrote about 'drawing to write', and how the close observation that comes with drawing can help focus the mind when writing.
In a sense, this is an exercise in narrowing the gaze.
At the other end, perhaps, is 'walking to write' - which allows the eyes to expand their line of vision and bring in ideas that don't come while we're observing too closely, or we're too inside the work rather than alongside it, as I find to be the case when I'm walking. The story comes along for the walk, but lets me wait for solutions to appear. A lack of focus creates answers, as well.
