Non-writers think the words just flow from a writer's pen like magic in some sort of blissful perfection. Not true. Although a writerly mind tends to focus (often too much) on minute details and obtuse observations, our thought are usually spat out onto the page just like everyone else's.
So this past week as I tackled my first bag of knitting yarn that arrived in skeins instead of balls, I had over an hour (that it took my to maneuver it into proper form) to contemplate how this soooo relates to writing. It's kinda like when you're stripping wallpaper or mowing the lawn and your mind has time to wander...to what? Well, writing, of course. And the dumping of first draft material onto paper is very similar to managing a jumble of strands into orderly fashion, no?
In the end, it's about having the tools - a swift here - and then practicing the process so that your muscles - in the case of authoring, your writing-muscles or freewill-capacity - remember exactly what they're doing as you put pen-to-paper. Training your mind to relax and let the words flow (unedited!) is what it's all about. Editing, perfecting, polishing comes later.
What's needed is akin to the aligning of disparate strands/thoughts/words into fragments/phrases/(dare I say) sentences. I'm most often a poet, so I don't even worry so much about sentences. Dig deep and dredge up the feelings because emotion that you, as writer, deliver to the page, your reader will find and feel from the page.
Practice doesn't have to make perfect...just get it done!
