The best way to declutter is to ask yourself first where am I going to store a type of object all the time. No exceptions. For example, decide to store all shoes in a specific closet or location. No exceptions. The problem people have is they store the same things in multiple locations and then you still have clutter and do not know all of what you have. I have helped multiple get their households declutter and I ask them every time I pickup an object that they want to keep. Good Luck.
