It's not often that I suffer from writer's block.
For me, it strikes when I have too much to say, and not enough time to say it. My head fills up with fragments of sentences and splinters of stories, none of it tied to any other piece or theme, just a great swirling structure-less tangle. All that mulch in my head is so busy growing such a multitude of different ideas that none of them can get a clear shot at the sunlight.
Blog posts and stories get tangled together, pairing off wrongly and spawning little mutant baby ideas, until my focus disintegrates and I find myself thinking re-tagging my mp3 library is a worthwhile use of my time right now.
I've never been at a loss for something to say, particularly, not when writing. I simply get choked by how much I want to say, or by how best to say it. (That last is easier to attack at least: write something appalling, and edit it mercilessly into something cogent, and call it done. (For some reason that tactic works much better on writing fiction than it does on writing a blog post, though.)) I want to write about silence, and breaking it; about conversations and confrontations; about the mechanics of a story, its structure and its heart; about innovation as opposed to invention; about people who can't give up and people who can. I want to finish that troublesome thorn girls story, and crank out some mileage on the faerie novel. I need to get that international report done for the dayjob, and prune back that tangle of further correspondence breeding in my in-tray faster than I can sterilise them.
Instead, so far, my mp3 library has sprouted a more comprehensive collection of cover art.
