I remember when my first novel was being proofread by a group of close friends. They were ruthless in their criticism (being the very best kind of friends!). It took me a while to realize that a reader’s not liking something did not necessarily mean that I was obligated to change it. “Why is the hero only five foot four?” one gal pal complained. Well, because he’s my hero and that’s how I chose to make him…and perhaps it determines who he is, how he thinks, and what he does. It turned out, of course, that she simply finds tall men attractive and short men repellant. So be it.

I consider myself a writer, yet have great difficulty concocting resumes or biographical pieces on myself. I think this is due to having to write “for an audience” or “for a market”.

I think, to answer your query, that much depends on WHY one writes. Do you have a message to impart, a point of view to express, an ax to grind? Or are you good with words and not in love with your work? Perhaps people who tend towards the second viewpoint are more marketable.
