Almost ten years ago (December 31, 2015), I wrote about "the houseboat philosophy". A summary would be that houseboats can only have so much weight on them before they sink. Thus, when one thing comes on board, something must leave. (Of course, a little allowance is made for temporary dinner guests.)
Of late, I seem to have been seeing an awful lot of advertisements for storage units. And I don't watch many programs with advertisements. It seems similar to those advertisements for stomach upset or feelings of bloat or being overfull. They try to address the symptoms and divert you away from the actual problems. Overeat? Have a pill to fight against the effects. Eat less? Don't even think about it (literally).
In the area of storage, there are always times when such is truly reasonable and necessary. Someone dies and their living quarters needs to be emptied to allow it to be sold or occupied by the next folks. No time to do the sorting, selling, and finding other places for items. And sometimes the storage may be used for something that is really used -- but not all of the time. Ski equipment in the summer is probably only excess stuff to have on hand. Camping equipment may only be used during the non-winter months.
But, most of the time, it is a matter of accumulation and overflow. Once again, if that overflow was treated as something to be dealt with in a timely fashion then temporary storage might be prudent and useful. But often it isn't.
For many of us, those items that pile up each have memories associated with them. How can I possibly throw away my kindergarten report card (from 60 years ago)? This was Great-Aunt Mabel's baby blanket, we have to keep that -- while none of the next generation have any memories of their distant relative.
Personally, one of my largest dilemmas is the amount of photos accumulated. Current, and future, generations may have no idea of this problem as almost all such is now done digitally. Get more and more storage. We're using this method -- but we still have thousands of photos that are not digitized. Photos of your grandmother as a baby. Digitize and trash it? Sure -- not easy. And if not annotated then the next generations will not have a clue as to who any of the people in those sepia-colored photographs might have been.
But accumulation has both its direct and indirect costs. Whether it is internal space or external storage, the accumulation requires space. Space costs money. If you are looking for something that is among 100 cubic feet (or 3 cubic meters), scattered all over, it is much easier to search for that item among 35 cubic feet (or a single cubic meter). Clutter is hand-in-hand with inefficiency of searches. I have "replaced" a lot of items that I have been certain that I had (and, possibly, later found) leading to duplication and unnecessary purchases. This is both frustrating and expensive.
Not everyone is happy to work towards minimalism -- nor is our economy oriented towards that philosophy. But, a bit of work towards eliminating excess (with both food and possessions) can make our lives easier and, perhaps, allow a bit more spreading of wealth among those who have need of it.
