Modern technology helps you to de-clutter in advance, if such is your preference. (Collectors need not apply, but your duty is to catalog your collection in advance, with hints on how to sell and not get "robbed" in the process.)
Consider. I have 700+ audio CDs, all ripped down to a chip. I have multiple back-ups, including one in a Safe Deposit box. I like to read, but 95% of my library is now converted to e-books, with removable chips, and once again, the same back-ups. There are other ways to shrink your "stuff". Photos? scan and save the scans. My brother occasionally gets "fancy" and makes "Ken Burns" style flows of photos with music from my music library. I scan all my paper tax related papers. and keep them on chip. Easy to add another year, every year. (And I have the tax booklets all the way back from 1981 - courtesy of the IRS!)
