A lot of this stuff is superfluous, just stacks sats and stay humble

Try to replace in part with an alternative form of content on the same topics, like books or podcast. Not only it will provide a better value/time spent ratio, but it will also "detox" you from the rush of checking SNS all the time

Only have your nsec on a VM in your computer

Great question. I have similar issues. I think the key is to make these addictive apps more difficult to access and less convenient, without making them impossible to access. Though I did just delete my podcast app... I would love a launcher app for my phone that would replace my (android) home screen. It would give easy access to a few select applications, that I choose. For instance, phone, calendar, etc. It would also allow me to open other apps that I want to limit (say a browswer, email, social media, etc). But I would only be able to open these apps after a challenge. The challenge would be something tedious like, "solve a 2 digit multiplication problem". The level of tedium could be adjusted. There's a phone app called Slim Launcher that is somewhat similar to this, except it's really easy to circumvent (just click on settings). I've also edited my hosts file to block access to certain websites. I have a trashy slow old unrestricted laptop that I use to access those sites on occasion. Here's a subreddit that https://old.reddit.com/r/nosurf/ that addresses some of these issues. It's a difficult question, for sure. Looking forward to hearing more ideas.
