Hillman on the Author's Battlefield
Anyway, that's a long way to get to this slyly revealing passage in that book in which Hillman talks about writing using military terms and concepts--not something I've ever thought about, or how I approached writing, but worth considering.
"Writing books for me is anyway much like a military campaign. I confess to fighting my way through with military metaphors. There is a strategy, an overall concept, and there are tactics along the way. When stuck, don't dig in; keep moving forward. Don't obsess trying to reduce a strongpoint by sheer force or laying seige. Isolate it and in time it will fall by itself. No pitched battles with the interior voices of saboteurs, critics, adversaries. A light skirmish, a show of arrows, and disappear into the next paragraph. Camouflage your own vulnerability, your lack of reserves with showy parades and bugles---remember everyone else is equally vulnerable. Pillage the storehouses of thought, refurbish old material and use it to reinforce your lines. Abandon ground you can't exploit, but when you've got an issue on the run, take all the territory you can."
