"Great wits are sure to madness near allied And thin partitions do their bounds divide." - John Dryde
I woke today at ten to four in the morning and headed straight for my workspace, pausing only to take my meds. I was interrupted by a text message from a server, but that's besides the point which is that even though I was half asleep I needed to finish the painting that I'd started.
The thing that disquiets me is not that I was compelled to the easel in spite of the early hour and lack of sleep, but that the desire to finish came from a backlog of images in my head...images that I needed to get onto some sort of surface before I lost them.
I have a small sketchbook I keep on me at all times for that reason, but it doesn't quite get rid of the anxious need. That only goes away after I've translated the sketch into the final medium, whatever it is.
Kay Jamieson came to mind, which led to a Google, which led to this article and the excellent quote at the beginning of this post. I couldn't put my thoughts about this phenomenon into words better than the writer of this piece, plus he includes links to the books I'd been looking for.
Side note: The post title is shamefully stolen from the title of one of Kay Jamieson's many thoughtful books.
