I spent an hour tonight updating the binder where I keep track of all my fiction subs, and I also sent out a story that's been waiting for some attention. Not five minutes after I'd finished with all that, I got a response from one of the subs that have been hanging fire for months. It was a rejection, but a nice one with an apology for the delay.
Obviously, I need to update my submission binder more often. It gives results!
