I didn’t start to appreciate writing short stories until fairly recently. I always viewed short stories as something “quick and easy” to write. Of course, they’re not easy to write at all. Just because they can be 5,000 words as opposed to 50,000 words doesn’t mean it’s faster or easier.
Another thing I thought was that writing novels was “better” for your writing. I figured the more I write, the more I would improve. Writing one long story isn’t the only way to “write more” though.
