The Courage to Be Happy by Ichiro Kishimi and Fumitake Koga is the highly anticipated companion volume to the bestselling The Courage to Be Disliked. In this book, the authors continue their exploration of Adlerian psychology, building on the concepts introduced in their first book to offer practical guidance on achieving happiness.

Using a dialogue-based format, similar to its predecessor, The Courage to Be Happy delves deeper into the philosophies of Alfred Adler, a 20th-century psychologist whose work emphasized the importance of personal responsibility, social interest, and the pursuit of happiness. Through a conversation between a philosopher and a young person, the book encourages readers to examine their beliefs, behaviors, and societal influences that may hinder their happiness.

The central premise of The Courage to Be Happy is that true happiness is not dependent on external circumstances, but rather on how we choose to view and react to those circumstances. It stresses the importance of accepting the past, taking responsibility for one's own choices, and being willing to change one’s mindset to foster positive relationships and a fulfilling life.

In this companion volume, Kishimi and Koga offer insightful, yet accessible, advice on how to create lasting happiness by letting go of self-limiting beliefs and embracing personal growth. The book aims to inspire readers to live more authentically, let go of the need for approval from others, and take charge of their own well-being.
