Nebula has been quite successful as far as I can tell. A whole bunch of educational YouTubers have moved over or were part of establishing it and honestly it works well. Videos can download to your device, the quality is the same, the app is a tiny bit janky but nowhere near as bad as all the ads etc on the YouTube app, and the cost is actually reasonable and goes in a reasonable share to the creators. I strongly prefer direct access to creators like this and also like on Patreon. Direct support means there is no advertiser in between to demonetise a video or have it taken down because it is controversial. You can’t even have a WW2 documentary on YouTube but you can have actual Nazis, but on Nebula you get analysis and history without Nike or Surfshark being reticent to sponsor a video.
I’m 17 years without alcohol, 16 without “le drugs”, and 15 without smoking. I still have issues in my life and challenges to solve but wow, all of those would be harder and more numerous if I still behaved like I used to. I had a fairly short period of massive excess and had a few lucky moments of clarity which resulted in me quitting it all one after another. My partner and I have been together since just after I quit drinking and I am really glad they never had to see me being my worst self.
My biggest takeaway is it really does get easier with time. The hardest times were within a short time of quitting. The longer I sustained the more ingrained the change became and now I would be stubborn and resist any sort of backslide.
