Q: If you want to get rid of clutter and are having difficulty parting with things because of sentimental reasons, doing this will make it much easier. What is it?
A: Take photos of the items.
This study found that those who took photos of items before dontating them were 15-35% more stuff.
This was win-win as people reclaimed some space and peace at home and also helped the local charity and thrift shops by donating.
