here is the thing... pretty much anything in your everyday life can be a "hobby" if you sufficiently hyperfixate.
you do not need to accept slop in any dimension. doesn't matter if it's socks, coffee, paint, baseboards, light bulbs, olive oil, whatever.
the amount of effort required to properly research niches has never been lower. you ostensibly have god in your pocket, the excuses are fewer and fewer by the day.
just one example: we need new desks.
if I google "standing desk" I get all of these desperate canadian companies trying to PPC ad me into buying their knockoff workplace furniture with horrific laminate wood grains.
instead, I can feed chat corporate workplace furniture catalogues and fully spec out a desk to whatever specifications I want. fully custom, made by Knoll. normally B2B procurement like this is a pain but from my first email I knew exactly what I wanted, all of the product codes, etc.
previously you had to be neurotic to live like this, today you can be a weird combo of tasteful, picky, and lazy.
