Well-Rounded Living From Taking an Inventory of all the "Stuff" in Your Life

Something I was experimenting with, making a list or "inventory" of all the "stuff" (physical or non-physical / digital) in your life, in order to make better use of it

Some "stuff" has been haphazardly acquired in my life, as gifts or things I've gotten without a plan on how to use them, or digital files I'll get to "one day"... having a list of these things makes it easier to actively manage them (get rid of unused / unwanted stuff, make more regular use of things I have that I may not use much that I want to use, etc.)

Anyone gained any insights from making an inventory of "stuff" in their lives?
