what the heck can I do?

I wake up thinking about my novel all the time. Things I can add for description and things about the seperate characters.

And then last night, bam! I got a new idea for a new novel. Ugh. Can't I turn this creative churning off? I can't keep thinking up new ideas for novels when I am still writing the first one.

Anyways, for what its worth here goes, it is a sci fi novel about a rape.

started the novel

Hey, yesterday I got the binder out and started asking myself questions about the plot and the characters of the story so that I can build an outline. So far, so good. I have written, as in HANDwritten a full page so far and am trying to decide where to start it. These characters have been with me for such a long time that I could literally start at their births, but that seems overlong and needless, I could start at the moment of crisis, which I most likely will, or I could start nearer to the end and flashback. These are just idle thoughts I have flitting through this interesting head of mine....interesting to me, at least.
I have named the characters...Inez, of the title, being the understanding latina widow, Anna, the owner of the Physician-assisted suicide clinic (honestly, have to find a better clinic type name), and Richard, the reason the 2 women strike up their odd friendship.
Physically, Anna is a certain blonde actress of my age that I admire, Inez is me and Richard is the same as B from my past.
Hopefully writing this out on a public post lights my fire and continues to make me write.
