I have "writer's block" at work. I'm trying to generate reams of documents that describe the next release of the product of which I am describing, and the forward progress is laborious and stunted. Walk away, come back, check some email, surf the internet, pen a few lines, then scratch my head on how to jump in. It's a similar process and exercise to creative writing, only the subject matter and technical details is different.
Here's to hoping a quick blog post helps to unblock my creativity, which would be handy for the big push needed to get these requirements documents over the finish line!
