As a photographer, streetlights fascinate me. They rise up illuminating the world. There are so many shapes and sizes. Some loom over a gray city alone.
Some pull together in threes
Some hold their own in the blurs of the night.
Some are patriotic. What else would you expect in Washington, DC?
Some look like sentinels. See the helmet held on by the straps?
Some are imposing and geometric.
I just can't resist them.
--Thanks to Lady Glamis for this picture she took of me while I was obsessing over one particular streetlight at the Smithsonian.
Application to writing? Go with what you love. It may not be for everyone, but, if it moves you, it will find an audience. (Most likely people like you.)
Someday I may have to do a book on the streetlights of the world.
