If I Didn’t Already Own It, Would I Buy It Today?
Just because something has been in your house for some time does not mean you would choose to buy it if you had the option. Therefore, you can let that clutter go.
Always Put It Away
Items in the home should have a proper place to help you stay organized. Now, if an item doesn't have a designated spot, do you want to constantly move it around to tidy it up? Highly unlikely! This relates to the One Touch Rule.
Need, Want, or Guilt
People hold on to items because they think they need them, want them, or feel guilty or bad about throwing them away. It surely helps to reevaluate your reasons for keeping stuff.
If This Was Covered in Dust, Would I Clean It?
Who would want to clean something unnecessary over and over? The correct response is that you wouldn't.
Appreciate Without Ownership
One cleaner settles for admiring rather than acquiring to stop clutter. They are content with admiring what they feel tempted to buy or keep.
Everything Is Just Pre-Garbage
This principle speaks to me personally because it is based on a principle I've always held dear: the meanings we give to, or place on things determine their worth and value.
