To de-junk, sort things into 3 piles: one to discard, a second to give away, and a third to put away.

Focus on one room or area at a time and if you want to set a time limit such as forty-five minutes a day (or some such block of time).
For me, the best way to reorganize a closet is to completely empty it and clean it . Then I return what I want to keep and throw away or give away the rest. In this way I don't just rearrange stuff, I actually make a difference.
