Exceptions to the above

They say the exception makes the rule and there is always room to step outside of "proper" writing methods.  Some ideas just need something different and that difference is part of the overall impact.  Just be aware there is a HUGE difference between a long-considered and well-written idea that breaks convention and a poorly planned effort that falls short of your goal.  The best metric to decide which is which involves your own response to what you have written: if you read it and only find it mildly interesting, your readers will probably find it boring.  You should always have a great amount of interest in what you've written; anything less means you should revise or rewrite the effort to strengthen what it offers.

Here's a basic example of what I find engaging, though it doesn't include very much action and contains no dialogue or conflict:

Jake closed his eyes and crossed his arms, enjoying the gentle sway of the car.  His friends hated his old Mockingbird, but he couldn't bring himself to get rid of it.  The new cars were more stable and rigid on takeoff, but not really any safer.  The 'Bird's thrusters were old school, with built in overcompensation that made the car sway ever so slightly as it took to the air.  Like getting rocked to sleep in your mother's arms, he often thought.  Made it so much easier to get in a nap as it flew to the destination.

I would consider this too short to publish, but I think it provides an emotional connection with vestigial memories of our childhood.  Very personal to me, as it reminds me of how the S-curves on the mountains would put me to sleep when my father would drive us home from a weekend at the cabin.  As a result, I think you can get away with something static, but the delivery must be powerful enough to impact the reader.

Wired magazine has an excellent series of contests called Found: Artifacts that provide visual views of the future.  The ones I remember most are just normal situations with strange text in them.  Love the images where the clue is in the ingredients or price tag or, my favorite for some reason, in an advertisement.  Always seems more impactful than a fancy scene full of flying ships.  Such an artifact might read like this:

Not quite Hemingway’s “Baby shoes for sale, never worn” but there is a delivery that gives hints to how we might approach the ownership and sales of synthetic life forms in the future.  Personally, I love this type of short fiction.  I'm not very good at it, but when it comes off well, it's like taking a really nice picture to capture the moment.  

I wrote these pages as an introduction, and they reflect what I go through when developing ideas, but they shouldn't be hurdles to your writing.  Good luck with your writing. Remember the basics, but always feel free to break convention and experiment.
