I am currently reading “Stolen Focus” too, and I was about to write here to recommend it because I find it very good and helpful. Even though I’m only 50 pages in (I started yesterday), it resonates with me a lot.
I’m also reducing my smartphone and social media consumption, mainly Instagram and YouTube. A couple of apps are helping a lot: Burnout Buddy and Opal (Opal is a bit expensive, so I switched to Burnout Buddy, but Opal has a helpful free Chrome extension). You can block Apps and Websites that way in case you are tempted and cannot control yourself.
My 2 cents! I don’t want to completely cut out YouTube, but I do want to reduce my consumption by 90%, which I’ve been successfully managing for a couple of weeks.
