I struggle with this.
I attach a physical thing to a memory and get sentimental about it all.
Throwing a thing away, donating it, or selling it becomes getting rid of a memory.
Even though that is not how it works.
So how can you decide if something is worth keeping?
This might be a good question to consider:
“If I didn’t already own this, how much would I spend to buy it?” This usually does the trick.”
