Remember, organizing truly never ends. Once you feel you are "done" go back to the beginning areas you worked on and reevaluate each area and give it a "tune up." If you have put in the right process of keeping things organized, you should have minimal work for each area. Keep it up and a full decluttering and organizing shouldn't be needed again!
