Worried about burning out early?

[pookel.livejournal.com]

I'm ridiculously excited about my idea right now.

This is an idea I had in 2004, plotted extensively at the time, and burned out on actually writing it before I ever got started. So, now I've revived it, chucked out a lot of the old plot, and and getting all kinds of new ideas for it.

But we've still got a month before November starts. I'm torn - should I plot like mad now and risk getting tired of it? Or leave it all in my head and risk being stumped when November starts?

I have won NaNo with a barely-plotted novel and won it with an extensively plotted novel, and I've lost it with ... well, two barely-plotted novels. Anyway, there's not a real pattern over whether planning helps me win or makes me lose.

So anyway, what are you doing in terms of planning in advance? Are there some things you're avoiding writing down? Or just not bothering with figuring out yet?
