Which means it's none too soon to contemplate. Two years ago I did, technically, get the outline done before November. Even a day or two earlier. In hindsight, however, I had not gotten it detailed enough. The last section was like pulling teeth. (Not exactly helped by the fact that I did it out of November to be sure.)
Which can be interesting, because my teachers would really disapprove: I don't even try to keep all the things of the same importance on the same level. True, there's only one level, but detail varies a lot. C. J. Cherryh's technique would not work for me -- first she writes an outline, then she writes a more detailed outline, then a still more detailed outline, and so on, until she finds herself putting in dialog, which makes it a first draft. Me, I've been known to put in dialog into the very first outline. How else can I be sure of getting that exact and gemlike line, or even if I'm just putting down that gist, that exact exchange between two characters for maximum drama? You never know, I might never manage to recapture that first spark of inspiration.
Sometimes you've just got to play it by ear.
