On the contrary, to me it appears that we are in agreement. You have found a method (to figure out what can stay) that works for you and I'm yet to find mine. I will consider if your method could work for me.
The method I mentioned is a way to set things in motion, and your brain unconsciously decides what to keep by getting it from that pile. Then you can give the rest (or some of it) away.
Hope it helps.
