I wrote a few short stories over the past few years, and I have shared a few of these with beta readers and asked for feedback. I have one that I decided was ready to go find a home, so I found a journal that I thought was a good match and submitted it. It was rejected.
I don't take the rejection personally. I know there are a lot of reasons to reject a piece, but that's the rub -- I can't tell if it was rejected because it's crap or for some other reason. I also can't tell if the rejection was a form letter or not. It was via email and the editor invited me to join their writing group. That could be a nice "hey, get to know us better" or it could just be stock. I can't tell.
I want to invest my time wisely. I know that even good stories get rejected and that it takes time to find a place to publish. I wasn't expecting to get work accepted on the first try, but I also wasn't expecting that I would suddenly falter in my feeling that this story was ready for publication.
How do I decide if I should spend my time re-writing this story, or if I should look for another place to submit it and spend my time writing more stories instead?
