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.
