That money is gone.
Holding on to an item you don’t use or need doesn’t get you the money back.
Yes, you spent ‘good’ money on it. (Is there bad money?)
And you either got value from the purchase or you didn’t.
Maybe it was an expensive item that you used many times so your cost per usage was quite low.
Maybe it was an expensive item that you never used, or only used once or twice.
Maybe it was on sale, or cheap.
It doesn’t matter.
The money is spent.
If you don’t use the item,
like the item,
only aspire to what the item represents:
Let it go.
Move on.
If you’re worried about wasting money;
remember that next time you spend ‘good money’ for something.
Be a more mindful shopper.
