Clothes I haven't worn in years, coffee mugs by the dozen received as gifts that I never use, knicknacks that seemed interesting or cute but not enough to pack or move, ball caps from events by the dozen in a pile ...
While some of our priceless collections are pure junk to others and probably need to go in the trash, some of the things like those listed above can have a value to others.
DW takes a dim view of excessive collections of 'might-be-handy-someday items".
From time to time DW gives me the "either-that-junk-goes-or-I-go" speech. I have thought hard about the two options on occasion, but have always gone for plan A, since I probably have more invested in DW.
If you itemize on your taxes, the items above can have some value even when you have to get rid of them. Donations to Salvation Army, GoodWill or such places are deductable (within reason).
First make a detailed list of the stuff that is actually worth giving away as you pack it into boxes like:
6 pairs mens jeans
8 mens t-shirts
1 black velvet painting Elvis
43 baseball caps
Next, take the stuff to Salvation Army (or other organization of your choice).
GET A RECEIPT (much easier to do if you have the itemized list in hand).
There is some cheap software (I use H&R Block's Deduction Pro) that will give you dollar values that IRS will find reasonable for your donations.
Last, KEEP THE RECEIPT.
I have found that this approach beats keeping all that great stuff for several reasons:
1> Your donations are used to raise money to help people
2> You are recycling
3> You are clearing space for even greater stuff
4> You are giving someone else the chance to buy your stuff and add it to their might-come-in-handy stash
5> You are keeping Uncle Sam's grubby paws off of a few dollar of your money
6> It is cheaper than a divorce lawyer
