I'll give you an example of something I've done recently which has made a big difference. Although, I don't have ideas on how to apply this to other aspects of my computer use (but open to ideas).
I listen to a lot of music. My teenage years/20's revolved completely around music. But I've gotten to a point where Apple Music/Spotify have become like Netflix to me - I have so much choice I don't know what to choose. I like to buy vinyl but it's expensive and not practical for most of my daily listening. I thought about it and realised that, for me, the time when music and technology merged for the best overall experience was the iPod (pre-Touch). I would mostly listen to albums I bought via iTunes (i.e. I cared enough about them to spend money and would listen to them a lot) and I checked out new music via Spotify (which was available in the UK in maybe 06/07) and then bought the stuff I liked on iTunes so I could take it with me on my iPod.
So I bought an iPod Classic on eBay. I deleted all the music I'd 'added' to Apple Music over the years leaving only my pre-streaming purchases (I also signed up for iTunes Match to backup and sync all my Bandcamp purchases + vinyl download card tracks). I've went back to my system of Spotify for new stuff, purchasing new stuff on iTunes, and syncing it to my iPod. It weirdly feels like a burden has been lifted having so much unnecessary choice removed. It's giving me a chance to get obsessed with the stuff I like again instead of quickly moving on to the next thing the algorithm throws at me. I highly recommend it. Currently thinking of ways I can apply this elsewhere in my life (e.g. purchasing TV/movies on iTunes instead of using streaming services but this could get very expensive very quickly).
My only purchases now are through bandcamp or at concerts.
All of which to say I have no idea how I ought to organize life around computers differently.
