I posted a few comments on the forums at JanNoWriMo — and then I proceeded to not even touch my computer at all until January was over. Why? Writer's block does that to me. Whenever I get blocked, my mind goes into the equivalent of fetal position. I sit in my living room recliner and think random thoughts that have nothing to do with whatever I'm supposed to be doing — or sometimes, like last month, I obsess over what I can't do. Which, in my case, was write enough notes for my '07 NaNoWriMo novel Bad Company that it actually (and finally) developed a coherent plot. Maybe I might even write some of it before NaNoEdMo...
What does it mean when I get writer's block? I don't touch the computer at all. Or any of my video games (Atari, Sega, PlayStation, etc.). I don't do any actual work on what I'm blocked on, even though I'm sometimes completely obsessed with it and even write notes on it in longhand, for whatever good that does me.
Anyway, my latest bout of writer's block is over and done with. Good thing I wasn't blocked for 4 straight months, like when I burned out on the first day of AugNoWriMo '08 and nearly lost NaNoWriMo that year (and even though I did win NaNo '08, the novel was completely unusable)...
