The continuation of It's a Helluva Job is going slowly. But it is going.
I would say that the thing I do most to enrich my imagination is read the works of other people. The only problem with that is that it takes me away from writing on my own works.
You're quite right that I have a full time day job (though I always hope that I will write a breakout novel. Of course to actually do that I know that I'm going to have to give up writing as a hobby.... which will disappoint my readers here. I have not yet made an absolute decision to stop writing as a hobby as I feel that I still have much to learn about the art and craft of writing. So you are in luck as to me continuing to post here as I complete works to the best of my ability for some time.
