The first impression this book gives me is a very practical and basic introduction to psychology. If you want to know some of the most basic knowledge of psychology, reading this book is a good choice. This is the most common psychology book. There are no psychological tests, no psychological stories, no human resources, and professional content in any aspect of society. It allows a person who has no knowledge of psychology to have the ability to step into the more profound world of psychology step by step. After reading this book, I found out that life really has psychology everywhere.
