80-90% of this book is making the argument against overuse of screens. It was preaching to the converted. I was already on board when I picked up the book. Perhaps the title should have been Why You Should Manage Screen Time, or similar. I had to re read the odd paragraph as some of the wording was unnecessarily convoluted. There is one scant chapter at the end which is practical, but perhaps you are like me already taking the commonsense approach.
