You know when you haven't had sex in awhile and after a time, you stop thinking about it because it hurts too much to think about and even masturbation becomes a dull routine? And then when you finally get to have sex again, it's like rabbits on crystal meth? You know the drill (pun intended). It isn't so much a "quickie" as it is an "immediate-ie." But then you're able to brush back the cobwebs a bit and say, "OH YEAH!!! Now I remember why we do that!" And the next time isn't so urgent. There can be more care, more touching, more... foreplay.
I find writing is the same. My NaNoWriMo experience was definitely one of "immediate-ie" speed. I was through 53,000 words in just over two weeks. People asked me how I managed to do that. I honestly don't know. Once I was in the groove, the words just came. It was the fastest I've ever written anything which tells me I was "pent up."
All these words may turn out to be the wrong words, I'm editing now and there's a lot of red ink, but at least they're out there now and not rattling around in my skull like... skull rattling things (yeah, so sue me!). I won't carry the sex analogy too much further, but I have to say that NaNoWriMo was a literary and creative orgasm for me (a big one!). All that pent up creativity that I was recycling into snark at my office in the form of snide offhand remarks and disdainful irritation at my colleagues has transformed itself into something much more constructive. And now that the dam has burst (so to speak), I find myself seeking creative outlets like a writing nymphomaniac (Ok, now you've gone too far!).
The juices are flowing, the ideas are twiddling around in my head, mixing and churning and I think I can get some of them out, on "paper" and maybe produce something worth reading one day. Or maybe not. But I'm still going to do it if for nobody else but me.
