Because a short story teaches you to economize. How to write a succinct beginning, middle, and end with no or minimal fluff.
Fluff = Unnecessary filler.

Short story writers I recommend:
Me. I have a number of short stories which you can find in my book list. 🙂 (Look left.)
Believe it or not, Pistol Pete Maravich~ I swear he wrote a collection of short stories. Read ’em when I was a kid. Good luck finding them. I sure as heck cannot.
Washington Irving (of Sleepy Hollow fame).
O. Henry (William Sydney Porter).
Edgar Allen Poe.
Sandra Cisneros. (I consider her novellas to be interconnected shorts.)
Chitra Banerjee Divakaruni. (Again, her novel,l Mistress of Spices, gives one a sense of interconnected shorts.)
I’d like to include more female short story writers, but women, at least according to traditional publishers, tend to write long. Or perhaps they aren’t published and promoted until they write long. But it’s more than that. It’s not sexism. You’ll notice most of those men are dead or old dudes.
It’s this~ in America the writing of a short story has become a lost art. To our literary detriment.
It’s also this~ The interesting thing? Over the past ten years erotica writers have mastered the art of the short story. Concise writing. Beginning. Middle. End.
