Suitcase, chest, drawers, yes - it's just the thinking and not having "possessions."
The bigger takeaway is learning what keeps you grounded or anchored. Nothing is wrong with that - can be family, can be cars, can be real estate/houses, can be business, etc.
The idea is you inventory your life and see what is the most minimal you need (haha, MVP basically.) and go from there.
You can do it for spending, you can do it for consumption via money, diet - eating/consumption/purchasing,etc.
It's fun, I enjoy keeping an inventory list, knowing what I have where and for larger valued items, e.g. $500+ I can put in last time usage so if I don't need it, I sell it - lower value items giveaway/free.
For me, I've live in the PNW too - and it's quite fun to just have a suitcase/duffel bag, and just camp out in my car or drive somewhere new and do that - or like I said above, hop on a flight and have everything I need for the duration of my stay.
I get it can sound boring or non-exciting to many people, but once you get into it - it really is fascinating. What things do you need for everyday life?
Up in the air had a great segment about it, https://www.youtube.com/watch?v=UsRP9EUrXjo I haven't read the book, but I should - I've been seeing it quite a bit.
