I have just received a rejection for another short story. This one was submitted to an anthology being produced in the USA for release as an ebook.
The editor advises that they received over 5,000 submissions to the anthology. My story apparently made it to the shortlist, so that was an accomplishment of a sort even if it didn't make the final cut. But all fiction is subjective, it does not mean that my story was crap. I just need to have another look at it before sending out once more.
This experience shows just how big the competition can be in the short story market, emphasising the need to make sure your story is the best that it can be.
