To quote loosely from the fairy-tale Goldilocks and the Three Bears: Someone (or something) has been sitting in my chair .... blocking the path to the keyboard.
However, I can't use the cat as an excuse for writer's block. Nor can I put her to work, cranking out the text. That I have to do myself. As someone who churns out text for a living (web content, marketing publications, science articles, technical reports, da-da-da-da), I've seldom been struck by writer's block. I do a lot of what I term "thrashing," however. Thrashing is the sort of restless activity that initiates the writing process. Checking the email, printing out background material, going through the background material with a yellow or orange highlighter, drinking lots of coffee. Stand up, sit down, fold laundry... It's all a prelude to putting fingers to the keyboard. Something eventually emerges to propel me forward: Sometimes the title for an article, or an opening sentence for a document. I don't outline (although maybe if I did, I could write like a demon, like Michael), so the thrashing around is apparently my way of revving the motor in preparation for the journey.
Writing fiction is a little trickier... and I often find myself dealing with the "muddle in the middle," where I'm not exactly sure where to go next. So, the thrashing about increases in intensity (as does my chocolate and caffiene consumption and overall grumpiness). I have no magic wand to wave or sage advice to offer to those who suffer similarly. For me, it seems a matter of putting the fingers on the keyboard, typing something to the effect of "I have no idea what's going on," and then writing whatever spills out next.
To make this post a little more (ahem) useful to others, I looked up "writer's block breaker" to see what I could find that might be interesting. Romance writer Roni Loren has a neat idea that she explains in her blog post "A Writer's Block Breaker: 30 Songs For 30 Chapters. " ... It's an approach that actually sounds rather fun. I wonder if one could use something like this to help frame a short story.
There are a bazillion blogs and sites that talk about writer's block and ways to overcome it. But I suggest you just "come along with us" this week at the LadyKillers and see what my compatriots have to say on the matter, starting with Michael A. Black's post just yesterday.
Finally, for your amusement, I offer this little video on Writer's Block. that I found on YouTube. In these days of computers, at least we don't have this fellow's problem!
