The 'Four Box' Method
Recommended by spruce.com and many others, the four-box method helps you categorise your decluttering, so you don’t spend all that mental focus on decision-making. The four boxes are ‘trash’ (you can add a fifth recycling box, if you like), ‘donate/sell’, ‘storage’ (things you need, but not often) and ‘put away’ (things you need often). This way, your tidying will have structure to it: simply put things in their right boxes, then rehome them afterward.
Surface Thoughts
If your surfaces are cluttered, it can really drag down your mental state, and make it hard to address the wider tidying problems in your home. This makes your surfaces a great place to start in any room, letting you get a clear head before you move onto the rest of your tasks.
