Corralling Your Memories
The thing that makes stuff more than… stuff is the sentimental value that’s attached to it. Material possessions are a reminder of a different time that has come to pass; it’s physical evidence of your beautiful memories. But, you can still have those memories without the burden of all those things.
Collect all the things that are memorable: cards, pictures, movie tickets, concert tickets, jewelry... anything else. Pick a box or bin with a lid to store everything in to give yourself a physical limit. Whatever you can fit inside that box is what you’ll keep. Otherwise, you can toss or donate anything else. If there is still something you want to remember, take a picture of it so you can still have that memory without the clutter.
