That realization - that you realize there's really nothing [worthwhile] for you to do - after getting over that initial break from your phone, is a magical threshold that I wish I'd crossed a lot sooner. The time and energy it frees up is so powerful, no matter what else you choose to do with it. Reading 4 books is incredible on its own but in this day and age it (and any other deliberate, non-scrolling activity) has incredible effects on your attention and emotional-balance, which I'm sure you've noticed.
Ecclesiastes would be an appropriate read.
Our minds seem to be more like LLMs than we probably like to imagine.
In some areas of life, technology and society have forced us to be more aware, of more things, more of the time. Our 'context' is filled with more things to consider, and attention is the window in. Sleep, schedule, and planning, helps to reset us and use context wisely.
Modern life forces a lot of context in, but we still have a lot of control over the rest of our daily 'attention windows' (like cutting out the excessive attention-grabbing media). It's kind of a rigid way to think, but there seems to be something there. We do have a saying afterall: 'what's on your mind?'
I appreciated the article: it was a good reminder to manage time wisely.
