I can't explain it but at the age of 33 I've become obsessed with decluttering in case I die abruptly and my wife is left with all my shit. Started selling a bunch of stuff and using the money for experiences and holidays rather than just shit. Feel so much better.
Just make sure your legal paperwork is in place as well. Powers of attorney, will and a notebook with all the boring financial information in. Then go forth and live properly. You’ll be one of the few!
