This is a really great book. I highly recommend it to everybody I know as a manual for being focused on the things that matter to you most. I first read hooked before reading this and was surprised by how effectively I was being marketed to. Though I quit social media a long time ago, and had been practicing some of the principles in this book, some other concepts were new to me. I found a lot of satisfaction in being able to address my internal triggers, having not understood their causes before. This book is applicable to everyone and I'm convinced it will help make the world a better place.
