From my perspective as a Christian, two sayings come to mind. First, Jesus:
"...one's life does not consist in the abundance of his possessions." - Ref.
And then the apostle Paul:
" I know how to be brought low, and I know how to abound. In any and every circumstance, I have learned the secret of facing plenty and hunger, abundance and need." - Ref.
I have found both of these sayings to be very true personally. I often struggle with the clutter that careless, disorganized possessiveness has brought into my life. And I also find that I've needed to be able to deal both with surpluses and shortages.
Thanks for another thought provoking article!
