Bedrot!
Create a "low effort reset" system
Have a basket or box where you can quickly throw things when your room gets messy. It's not perfect, but it stops things Spiralling.
Combine packaging for makeup and Skincare products, minimalise Space any duplicates take up by repackaging them into one Container.
Use the "would I choose this again?" test
Instead of "do I use this," ask yourself if you'd pick it today. It cuts through guilt, especially with Clothes you should like but don't wear.
Set a timer (10 to 20 minutes max)
Decluttering doesn't have to be a full day event. Short bursts are way more Sustainable.
