Most authors I know (both independent and traditional) see the novel as their main creative outlet. It has the substance, gravitas and size to mark it as a major achievement. Few of them focus on shorter works as a beneficial aspect of their craft. (I include both short stories and novellas into this discussion See Just How Long is a Novel and How Much Should it Cost?) I feel that independents, even more than traditional authors can get enormous benefits from writing short fiction. I've identified ten virtues of writing shorter stories that cover the business, craft and lifestyle of writing.
2) Cost benefits: One of the major costs in independent publishing is editing (See How to Find an Editor without Going Insane). The editing cost for a 120,000 word book can easily be $2,000 or more. The price is often based on word count, so a 15,000 word story might only cost $240 under a similar pricing model. This lower price offers flexibility on two fronts. First, you're more likely to try different editors if you know the cost associated with each one isn't that much. Second, the release of each book won't take such a huge chunk out of your limited personal budget. There is an increased cover cost for multiple books (See the Mystery of Cover Design) but there are ways to keep those costs substantially lower than your editing costs.
3) Sales benefits: The popular wisdom about independent publishing is that the more products you have in the market, the easier it is for readers to find you and the more success you'll have in the long term. The problem with that is that it might not be feasible to get 10-15 novels out in a reasonable period of time. Releasing 10-15 novellas on the other hand is a more manageable production plan (See What's Your Publishing Plan?)
4) Playground for Ideas: If you're playing with a certain characters or scenarios for a larger work, but you're not sure if you want to tell that story over an entire novel, then a short story can help you explore the narrative potential. If you get to the end of the short story and you're itching to write more, go ahead. If the idea fizzles after 10,000 words, then you can avoid wrestling with the concept for 30,000 to 40,000 words before you realize you've written yourself into a space that you can't get out of.
6) Building blocks: I work under the concept that the chapter of a book is a mini story in its own right that includes a beginning, turning point and end (See Analysis of Story Structure Part 1: The Chapter). The only difference between short stories and chapters is that the chapter needs an internal consistency that also serves the broader book. Writing short stories is great practice for manipulating the individual elements of a novel that can be strung together to complete the story in the same way a season of a TV series is made up of discrete episodes.
8) Greater sense of accomplishment: When I look on my author page on Amazon, I feel better when I have more titles up there. The bigger catalog gives me a sense of progress and productivity that inspires me to write more. I don't know if I would get the same sense of accomplishment if I only saw my novels.
9) Creative freedom: When you know all your writing isn't tied up in one project, you can take risks. You can explore different genres, perspectives and ideas. You can push concepts farther than you normally would without sacrificing your main books. These might be stories that you never even release, but the creative freedom that they give you will come back and make your main stories even better.
If there is a downside for releasing short stories, it is their length in relation to their price. With many independents selling full novels for $2.00 less, some readers and writers might reject the idea of selling 15,000 words for $.99. While I might disagree with the $.99 novel concept, I understand the economic problem it creates.
The Vice of Short Stories
My solution is to release a series of short stories in an anthology that is cheaper than the cost of all the individual stories. For example, I released an anthology of related short stories called Smooth Operator in 2013. The book contained five short stories and one novella for a total of 65,000 words. If I released each one individually, the price of the set would have been $7.99. I released Smooth Operator for $4.99 or 40% off the individual story cost. It's still more than the $.99 novel, but I don't believe in selling full novels for a buck.
Do you write short stories in addition to or instead of writing longer novels? Do you do it for some or all of the reasons I listed, or do you have another rationale? Please share in the comments below.
