The definition of “addiction,” and what people can become “addicted” to, are hotly contested issues. In everyday conversation, of course, people throw around the word “addicted” a lot, as in, “I’m addicted to Game of Thrones.”
Addiction, whatever it might be, is a subject that’s related to my current fascination: habits. As I explain in the introduction of Better Than Before, my discussion of habit formation doesn’t cover addictions, compulsions, nervous habits, or habits of mind. Nevertheless, I did a lot of reading and thinking about addiction, because it’s a useful area to consider.
