Ok, I've done all my physical gathering. But the Mind-Sweep is taking forever. Just as David says, when I started writing things down, my brain offered me more and more. I'm up to a couple hundred items and although it's slowing down, I'm still getting these little trickles of "oh wait! here's a few more!" Should I just stop myself and start in on the Processing phase, maybe allowing myself to keep adding if more things come up? Or should I first wring my brain dry?
