Writer’s Block affects to us all from time to time. How it's handled depends entirely on the writer's deadline.
I don’t have time to play around; I compose an episode of my serial every week. This means I need to work through the problem. For sure, what I write is crud; but that’s okay. By the time the work is rewritten and edited, it will shine.
If your schedule is not so tight, take a break. Maybe a walk will help, perhaps a nap. If that doesn’t work you can always try again tomorrow.
About the time my zombie novel self-destructed, my creative urge folded and shuffled away. I wanted to write – I love to write – but I couldn’t face the thought of starting a new novel. Instead I joined Hub Pages.
On Hub Pages I wrote a series of product reviews. Mostly I evaluated software, putting the various applications through their paces and composing in-depth reports. My one non-software related product was an inexpensive steam cleaner. I carefully photographed each part and tested the cleaner on every surface I could think of. It’s still a popular review on Google.
I toiled for three months on Hub Pages, composing a total of sixteen reviews. The end result? About two dollars per month, a good grasp of technical writing… and a renewed urge to start a novel. If you crash and burn, you should try another form of writing. Eventually you will come out of your funk and, in the meantime, your skills will continue to improve.
