Although Jennifer Jacquet’s book “Is Shame Necessary?” focuses on how to use shame as a tool, it actually illustrates a much, much larger principle. Emotions aren’t good or bad. They’re tools and like all tools they can be used appropriately or inappropriately. There’s a job for a hammer and it’s driving in nails. If you use a hammer to clean your teeth, you’re going to have problems. The key with emotions is training them to be appropriate so you use the right emotion for the situation.
