I got to a point a few years ago where I found I had too much crap I did not use. My motivations for selling what I don’t use range from not wanting others to clean up my mess after I die to wanting to release money from stuff I have not used in years to get myself a new motorbike, mobile and laptop. The whole process is incredibly therapeutic.
I still need occasional clear outs. I still buy things, and stop using old things. Not a bad thing, consumerism culture is crap, but so is not having nice things.
