Sometimes I'll just put everything in my way into a cardboard box (for instance, everything on my desk, or the majority of a cluttered shelf). I write the date on the box and put it in a closet. The rule after that is I can take things out of the box if I need them, but I can't put anything else in. Any time I find a box with a date more than 1 year old I just donate the whole thing to a thrift store without looking inside.
