This book is essential reading. I can't stop thinking about it or talking about it. I particularly appreciate the way the book breaks down what appears to be a wild lack of willpower (I'm looking at myself!) into its component parts of behavioral addiction. I am thinking differently about the consequences of my screen time (and my children's) and about the approaches I take to curb my excess. Well-written, well-researched, well-timed. I will be giving out many copies of this book to family and friends!
