No, what's going on here is that I am deliberately trying not to start seriously working on a novel right now.
Because in addition to all those ideas and outlines and thises and thats, I have a novel (Thermionic Night) that is currently working its way through alpha readers. After that will be revisions. Then beta readers. Then revisions. Then submission to an editor (I already know which one, and if she's not the right person for this book after all, I will cry -- I'll move on and submit it elsewhere, but I think I know who ought to see it first, and if I've done what I want to with this book I think she'll like it).
I also have the completed rough draft of another novel, currently called Sampo but possibly being renamed. Since it's the sequel to the aforementioned Thermionic Night, I can't productively revise it (to give to alpha readers, revise, give to beta readers, and revise) until I've got TN into something closer to its final mode.
And in addition to that, I have four stand-alone novels and the sequel to one of those four sitting on the desks of three different editors waiting for attention of various hopeful kinds.
As a result, I am extremely reluctant to start the draft of another book right exactly now, when I'm hoping my alpha readers will be getting back to me within the next month. I don't want to get going and then stop again, and I don't want to put off revisions on TN because I'm caught up in something new, because that's not very productive behavior. As a result, not starting a novel right now seems like the right plan in every way.
Every way except the "my brain is going to implode and/or start gibbering" way. I'm not sure when that starts trumping other logic. At a certain point what I "should" be able to do or refrain from doing in my writing is not as relevant as what I can do or refrain from doing.
You know about inertia. Well, even as tired as I am right now, I am naturally a Body In Motion, not a Body At Rest. And the Motion is in some pretty specific directions, and I'm just not sure how this will work.
I hope that makes some sense. If it doesn't, go ahead and ask.
