I have such a problem trying to decide whether or not to keep a particular item. I am one of those people that thinks, "I might use it someday, even though it's been 11 years since I last touched it." and searching through some help on the internet, I found this good tip:
Ask yourself these questions over the item:
1. Would you want to frame and display it?
* Yes = Keep.
* No = See step 2.
2. Would you want to take a picture of it?
* Yes = Take picture, get rid of item.
* No = Get rid of item.
If you can take a picture of something that you want to remember, but can't use - do so. Put it in an album with a label. But let it go if it's taking up too much space.
I love that idea!
