I have just officially begun writing what I hope will be a new novel.  Interestingly, it isn't any of the ideas I've been percolating on.  It's a new thing that just serendipitously presented itself to me and I just decided to start on that.  I did two pages just now, and now I shall have to get serious and do my usual few pages of notes in lieu of an outline, which I don't like to do.
I've been going back and forth on my several ideas, and the one I kept leaning towards was a comic/romantic story.  But I didn't love the idea of it so kept not starting on it.  Then I got this new idea for a comic/romantic story, and this one seems right to me.  I had fun starting it, and now we'll see where it takes me.  Two weeks ago, I'd started a little children's book - I may try to do them concurrently, just for fun.  The children's book would be fairly short.
