I just cleaned out a supply closet and decided not to trash everything but separate every scrap of material to its closets material (paper, plastic, metal, ect.).
I actually think it was easier than putting stuff straight to trash. Once the opportunity for the item to be recycled was placed in my head, I found it easier to stort through and discard what needed to go. Way less struggling. The idea it would be used somewhere else meant less anxiety about destroying a "perfectly good thing" (they weren't good things, just junk, but in my hoarders mind...).
In one day I think I got rid of more clutter and emotional junk that I had in over a decade. All by taking a few extra steps that, in retrospect, was more complicated in my imagination than practice.
