A lot of us have been taught by our parents (and especially grandparents) to hold onto stuff because “you never know when you need it”. Their mindset is right…most members of the older generations (depending on the geography) have experienced much more scarcity in their lives than we can imagine.
The way of life was different back then:
1. the dangers of war or political turbulence were more present
2. goods were much more expensive and it took longer to acquire them
3. goods were of better quality and longer lasting
Those and other reasons resulted in people keeping a lot of (possibly) useful stuff. We need to realize, that there wasn’t too much stuff, to begin with. But that’s not the case nowadays.
And yet, though in different circumstances, we were brought up by the same mindset.
Goods are so easily, so cheaply available to us all the time (at least in the 1st world countries and also in a lot of the 2nd world with a bit of higher price) .. the paste of life is changing and with one-click orders from Amazon and “free” second purchases, we don’t even realize how much stuff we have around us.
Decluttering is part of living in a consumeristic society. If you have trouble decluttering because of those old sayings of your grandmother, have a look first whether you live the same life she did.
