This was fascinating and I can't stop talking about it. Read it, friends! One of the biggest takeaways I got from the book is that we NEED to learn (and teach our kids, students, etc.) healthy coping methods to deal with stress, depression, anxiety, loneliness, boredom, etc.

"[A] substance or behavior itself isn't addictive until we learn to use it as a salve for our psychological troubles. If you're anxious or depressed, for example, you might learn that heroin, food, or gambling lesson your pain. If you're lonely, you might turn to an immersive video game that encourages you to build new social networks." Addiction happens when our brain learns that a chemical or behavior is critical to our emotional stability, even though it comes with other negative or destructive side effects.
