I don't usually sweat on stories.
Once they're written I send them off and do my best to forget them. At some later point I hear back, either a rejection or acceptance, and I'm either happy and beaming for a day or so, or annoyed for about five minutes. With a few rare exceptions, the days of stewing for days over rejections are long gone.
Mostly I have some idea as to when I expect to hear back from the editor or publisher. The submission guidelines give some clue of how long they expect to take. Other websites such as Duotrope or The Grinder keep data on submissions so a writer can anticipate response times.
But this week I've actually been checking my email a little more often than usual. I have six stories out, and most of them appear to be overdue a response, based on the data I'm seeing online. These are stories I have high hopes for, and I'm keen to receive a couple of acceptances.
But there's danger in reading too much into long response times. No news, after all, is nothing but no news.
In the meantime, I'll be over here refreshing my email.
