I hereby promise to write and submit a short story to a literary magazine.
That's an easy promise to make, because I've done that before. I've got the rejection emails to prove that I've tried it several times. One of my short stories has been printed multiple times and carefully plastered with notes from my critique group. I even have a couple of publications.
But this time, I'm promising to do it carefully following the suggestions in Let's Write a Short Story by Joe Bunting. There's a real world out there, though, and I also have a few articles I've promised to write for three different magazines, as well as a tax return to prepare and file, so this might take a while.
