As any of my fans know, I have yet to write a novel. I am in the middle of one right now, but I have yet to publish one. I have spent the past three years working on shorts works, and to this day have published 26 or so short stories and 4 novellas.
Now, I did this for one main reason: exposure. In the time I spent working on these shorter works, I could have written two or two and a half books. But then I would have had 2 or 3 works published instead of the 16 or so collections and novellas I have available. Was it the right choice? Who knows.
