Why do it?
What separates writers from non-writers? Part of it is the same thing that separates readers from non-readers; the rhythm of the words, being transported, having a story told to us (fiction) or new information to expand our knowledge (non-fiction). The writer provides the reciprocal, of course; writing the poetry of prose, telling a story, imparting knowledge.
For some, writing can be analogous to exercise. To begin with, we have simple goals of looking better, gaining stamina, maybe a health insurance investment. But, once into it, the doing becomes its own reward (read, endorphins kick in). Some get driven to be gym rats or running junkies beyond what will accomplish the original goal of a slim waist, lower blood pressure, et al, and just get into it for the pleasure of working up a good sweat or what comes with transposing brilliant images and thoughts to paper. Like gym ratism, some writers feel compelled to drive themselves with daily word goals, let’s-write-a-novel-in-a-month or other inventions of masochism. I’m not one of those people.
Personally, I enjoy the creation of a story that illuminates places, situations, and thought processes with word play knowing that it is keeping my axe sharp and may, just may, provide entertainment or elucidation for others. But, a literary Iron Man competitions? Not this boy.
