I don't use any of my stuff, it's just for LOOKS.

Net worth speaking, 20% or so. Housing is expensive.
Excluding my apartment, public infrastructure, the equipment at work etc, reasonably close to 100%.
Public services alone would drop the percentage down to ppm levels, I use them all the time.
I guess we all own public infrastructure through the magic of taxation, but I'm basing this breakdown on sole property ownership.

prob less than 5:) percent. i have alot of shit..:)

idk, half? at least. I didn't realize how few things I had until my friend just moved in with me and she has about 4x as much stuff as I do

I have too many things I don’t need.

Actually, most of them! In the past few months, I've watched a few of Marie Kondo's episodes as well as exposed myself to minimalism and fast fashion documentaries. All of them have shown me the dangers of consumerism and hoarding habits. Overall, I got rid of a third of my total belongings in the past few months and it's honestly made a big difference for my state of mind and levels of peace and contentment.

Um, I'm going to define commonly as once per week and say half

My style of living is minimalist, nevertheless the things I commonly use are still only a fraction, like e.g. an estimate of about 20%.
