A little book for big feelings.
Informative and accessible, The Book of Knowing is a friendly, therapeutic guide for teens to understand and control their feelings. In 2015, clinical psychologist Gwendoline Smith began a Tumblr blog under the pseudonym Dr. Know. Her Gen Z-friendly approach to CBT (cognitive behavioral therapy) resonated, and the idea for this book was born.

With lively art, tangible advice, and immersive activities, this book is a handy guide for dealing with big feelings that provides humor, kindness, and manageable strategies for issues that can sometimes feel out of our control.

Overthinking, ruminating, worrying: bestselling author Gwendoline Smith explains this common form of anxiety and offers helpful advice for overcoming it.
Psychologist Gwendoline Smith explains in clear and accessible language the concepts of positive and negative overthinking, the truth about worry, and how to deal with the “thought viruses” that are holding you back.

Based on cognitive behavioral theory, this book will help you combat anxious thought patterns in all areas of your life: from your personal life to relationships and work.
