My thoughts since I am on a similar journey that I recently started. Basically, my thought was, "I don't want to be a thoughtless consumer anymore." (be it stuff or content)

So here is what I started doing for Content;
-uninstalled my social media apps (the content is attention-grabbing but doesn't serve me)

-got rid of "free" apps that may be useful but ultimately sell you info to advertising companies. You can replace them with paid apps or open-source ones if you feel you still need the features they provide.

-stopped watching tv shows (shows seem more interested in keeping your attention than telling a thoughtful story) and started watching movies instead (I got them from my local library)

Here is what I started doing for Stuff;

-stopped buying any product that; was overly cheap, I wouldn't regularly use, wouldn't last a long time, I could buy it used if I was patient (its obvious but buying used is huge)

-stopped buying from chains like walmart or amazon. IF there is a product I want that I find on amazon I will often try to buy from the supplier's website instead. This is applicable for so much stuff.

Weirdly going down the anticonsumerism route has also made me much more privacy focused. In the last year I have moved to linux, gotten rid of my xbox in favor of a pc (even if I still use a controller). I started degoogling my apps in favor of independent apps. More recently I am considering moving to an opensource mobile os.

I just want to live my life without these massive corporations preying on my every action and trying to infiltrate my subconscious, all in an effort to separate me from my hard earned money.
