Welcome to our summary of The Courage to Be Happy by Ichiro Kishimi and Fumitake Koga. A compelling work of philosophical self-help, this book serves as the sequel to The Courage to Be Disliked. It continues the Socratic dialogue between a wise philosopher and a skeptical youth, who returns three years later struggling to implement Adlerian psychology in his life as an educator. The book’s central purpose is to bridge the gap between understanding happiness and actively choosing it, focusing on the courage required for love, building equal relationships, and achieving true self-reliance.
Part 1: The Bad Boy and the Good Girl
The scent of old paper and tea filled the Philosopher’s study as the Youth entered. A single lamp illuminated the old man, who sat surrounded by books, his eyes kind but penetrating.
PHILOSOPHER: Welcome. You seem troubled tonight. The weight of the world appears to have settled on your shoulders again.
YOUTH: It has! Master, your theories are beautiful but useless in the real world. I tried to apply your Adlerian principles at the school where I volunteer, and it was a disaster. There’s one boy who is a nightmare. He disrupts the class, picks fights, ignores instructions—a classic ‘bad boy.’
PHILOSOPHER: I see. And what is your conclusion about him?
YOUTH: It’s obvious, isn’t it? His home life is a mess, his parents neglectful. He’s acting out because of past trauma. He is a product of his environment, a victim of cause-and-effect. What else could it be?
PHILOSOPHER: You are clinging to etiology, the study of causes. You seek a simple ‘A leads to B’ explanation because it absolves everyone of responsibility. Adlerian psychology discards that. We do not ask, ‘What past event caused this behavior?’ We ask, ‘What is the goal of this behavior?’ This is the principle of teleology.
YOUTH: A goal? What possible goal could he have besides creating chaos? He clearly enjoys seeing the teachers frustrated!
PHILOSOPHER: You are close. His behavior isn’t random; it has a clear purpose. All problem behavior, especially in children, is a misguided attempt to secure a sense of belonging in a community. When a child feels they cannot gain a place through constructive means, they will seek it through destructive ones. This unfolds across what we call the five stages of problem behavior.
YOUTH: Five stages? It sounds like a pathology.
PHILOSOPHER: It is a sickness of courage. The first stage is a demand for attention. The child acts cute, makes jokes, or performs well to be noticed. Their goal is to be special. When this fails, or when the praise stops, they may escalate to the second stage: provocation. This is where your ‘bad boy’ likely is. He misbehaves and breaks rules. Why? Because even negative attention is still attention. For a child desperate to be seen, being scolded is far better than being invisible.
YOUTH: So when I rebuke him, I’m giving him exactly what he wants?
PHILOSOPHER: Precisely. You are playing your part in his drama. If you continue to scold him, but he still feels unheard or unseen, he will escalate to stage three: a power struggle. He will openly defy you. His goal is no longer just attention, but victory. He needs to prove that he is in control, that he cannot be bent to your will. If he loses this struggle, or feels humiliated in the process, he will progress to stage four: revenge. Now he will engage in more malicious behavior—vandalism, hurting others—to get back at those who he feels have wronged him. His message becomes, ‘See how I can hurt you because you hurt me.’
YOUTH: And the final stage?
PHILOSOPHER: The last and most tragic stage is the proof of incompetence. The child gives up completely. He tells himself, and everyone else, ‘I am worthless. I can’t do anything right, so don’t expect anything from me.’ He will intentionally fail tests, refuse to try, and retreat into a shell of manufactured uselessness. It is a desperate, final attempt to secure a place by proving he is so uniquely incapable that he requires special care and lowered expectations. It is a profound cry for help that has lost its voice.
YOUTH: This is bleak. What about the opposite? The ‘good girl’ in the class? She is a model student, does everything she’s told, gets perfect grades, and always seeks the teacher’s approval. Surely, she is the ideal!
PHILOSOPHER: Is she? You are falling into the same trap of only looking at the behavior, not the goal. This ‘good girl’ is not acting out of self-reliance or a love of learning. She is acting out of a desire for praise and a profound fear of punishment. She has simply discerned the quickest way to get the attention she craves: perfect obedience. This is the tyranny of the ‘good child’. She is not free. Her behavior is entirely dependent on the judgment of others. If the praise stops, her entire sense of self-worth will collapse. The ‘bad boy’ and the ‘good girl’ are two sides of the same coin. Both lack the courage to be normal, to be themselves, and instead pursue a sense of belonging through the validation of others.
Part 2: Why We Must Not Praise and Must Not Rebuke
YOUTH: I can’t accept that! Not praise good behavior? That’s absurd! Praising a child who does well is fundamental! And not rebuking the boy who is terrorizing the classroom? That is pure negligence!
PHILOSOPHER: Your reaction is understandable. It challenges our society’s core methods of control. But let's think more deeply. First, let’s examine the problem with praise. When you praise someone, you are passing judgment. You are saying, ‘You have met my standards. You have done well.’ This act inherently creates a vertical relationship. One person is the judge, the superior; the other is the one being judged, the inferior. Praise is a tool for manipulation by a superior.
YOUTH: But it makes people feel good! It’s motivation!
PHILOSOPHER: Is it truly? Or does it make them dependent on the next dose of validation? A person raised on a diet of praise does not learn to evaluate their own worth. They are constantly looking over their shoulder, asking, ‘Am I doing a good job? Do they approve?’ They become praise-addicts, unable to function without an external judge. This is the opposite of self-reliance.
YOUTH: So praise is out. Then what about its opposite? We must rebuke bad behavior. We must punish it.
PHILOSOPHER: What does punishment teach? Think of the boy in your class. When you rebuke him, does he reflect on his misdeeds and vow to be a better person? Of course not. He feels resentment. He thinks, ‘I got caught,’ not ‘I was wrong.’ Punishment only teaches fear and escalates the conflict into a power struggle. He'll just hide the behavior better or defy you more openly. You're not solving the problem, you're inflaming it.
YOUTH: Then what is left? If I cannot praise and cannot rebuke, am I to do nothing? Just stand by and watch?
PHILOSOPHER: No. There is a third way, neither a carrot nor a stick. It is the path of mutual respect. The alternative to praise and rebuke is encouragement.
YOUTH: Encouragement? Isn’t that just a softer word for praise?
PHILOSOPHER: Not at all. Praise is a vertical judgment of an outcome. Encouragement is a horizontal expression of support for the process. It fosters the courage within a person to overcome their own challenges. It does not evaluate; it appreciates the effort and acknowledges the person’s value as an equal.
YOUTH: Give me a concrete example. The ‘good girl’ hands in a perfect test paper. What do I say instead of ‘Good job, you’re so smart!’?
PHILOSOPHER: You focus on gratitude and contribution, which are horizontal expressions. You might say, ‘Thank you for studying so hard. Your effort helps me understand how to teach better.’ Do you see the difference? You are not judging her intelligence. You are expressing gratitude for her contribution as a fellow member of the community. Or you could focus on her internal feeling: ‘I can see how much work you put into this. It must feel great to see it pay off.’ This helps her build self-worth based on her own effort, not on your approval.
YOUTH: And for the ‘bad boy’? When he disrupts the class, what do I say instead of ‘Stop that right now!’?
PHILOSOPHER: You use what we call ‘I-messages.’ Instead of an accusatory ‘you-message’ (‘You are being disruptive!’), you express how his behavior affects you, without judgment. ‘When you shout during the lesson, I feel distressed because it makes it difficult for others to learn. I need your help to make this a good classroom for everyone.’ You are not attacking him. You are stating your own feelings and inviting him to be a cooperative partner. You are separating the person from the deed and treating him as a comrade, not an enemy to be subdued. This is the first step in building a horizontal relationship of equals.
Part 3: From the Principle of Competition to the Principle of Cooperation
YOUTH: A horizontal relationship… treating him as a comrade? Master, the world is not cooperative; it’s competitive. From school to work, we are constantly graded and ranked against others. To pretend otherwise is naive.
PHILOSOPHER: Is it? Or is this competitive worldview the very source of our unhappiness? If you believe life is a competition, then by definition, everyone else is your rival. Every other person is an enemy to be defeated or a threat to your standing. Through this lens, how can you ever feel at peace? How can you form a genuine connection? You are perpetually on guard, celebrating others’ failures and fearing their successes. True happiness is impossible in such a state.
YOUTH: But that’s how it feels! When I argue with someone, I want to win. I want to prove my point. I need to be right.
PHILOSOPHER: And when ‘being right’ becomes your goal, the discussion ceases to be about truth. It degenerates into a power struggle. You have entered the arena of competition. The other person is now your adversary, and their surrender is the only acceptable outcome. The substance of the argument becomes irrelevant; only victory matters.
YOUTH: I admit, I’ve been in many such arguments. They leave me feeling exhausted and bitter, even when I ‘win.’
PHILOSOPHER: Because you have damaged the relationship. You won the battle but are losing the war for happiness. To escape this destructive cycle, you must break the cycle of fault-finding by being the first to withdraw from the power struggle.
YOUTH: How? By just giving in? By letting them be right when I know they are wrong?
PHILOSOPHER: By simply admitting fault in the way you conducted yourself. As soon as you realize a discussion has become a power struggle, you can say, ‘You know what, you have a point. I apologize for getting so heated. Let's start over.’
YOUTH: But that’s admitting defeat! It's humiliating!
PHILOSOPHER: Is it? Saying ‘I was wrong’ is not defeat. It is not a concession of your point, but a withdrawal from the pointless game of winning. It is a powerful tool to de-escalate conflict and show that the relationship is more important than being right. Anyone can get trapped in a power struggle, but the one with the courage to end it is the true victor.
YOUTH: So I abandon competition… what do I replace it with?
PHILOSOPHER: You replace it with the principle of cooperation. You begin to see others not as rivals, but as comrades. You see humanity as a vast, interconnected community. In a cooperative community, there is no vertical hierarchy of winners and losers. There are only different people with different strengths, all moving forward together on a horizontal plane. Your colleague is not your enemy in the race for promotion; they are a comrade with whom you can achieve a common business goal. This shift in perspective is the foundation for all healthy interpersonal relationships.
YOUTH: To see everyone as a comrade… even those I dislike?
PHILOSOPHER: Especially them. It requires immense courage, but it is the only way to find a true sense of belonging and begin building a cooperative community based on mutual respect.
Part 4: Give, and It Will Be Given to You
YOUTH: Comrades, cooperation… this is fine, but what about my individual value? My career? I work hard, and I want to be recognized for it. I want to feel that my existence matters.
PHILOSOPHER: Of course. The desire to feel valued is a fundamental human need. But we often look for that value in the wrong places. You ask about your career. What is the true purpose of work?
YOUTH: To earn money. To support myself, my family, to build a future.
PHILOSOPHER: Those are secondary benefits. The true meaning of work, in the Adlerian sense, is contribution to the community. Whether you are a baker, a doctor, or a street sweeper, the essence of your labor is that it serves others. Earning money is simply the social mechanism for this exchange of contributions. When you see your work not as a means to a paycheck, but as an end in itself—a way to be of use to your comrades—your entire relationship with it changes.
YOUTH: But to contribute, to cooperate, to build these horizontal relationships… it requires me to rely on others. That is terrifying. People are untrustworthy. They will let you down and take advantage of you.
PHILOSOPHER: You are confusing two very different concepts: confidence and trust. Confidence is conditional. It is a belief in someone based on their past actions or demonstrated abilities. You have confidence that a skilled surgeon will perform well because of their track record. It is rooted in evidence.
YOUTH: Exactly. And most people haven’t earned my confidence.
PHILOSOPHER: But a deep interpersonal relationship cannot be built on the shaky ground of confidence. It must be built on the bedrock of trust. Trust is unconditional. It is the decision to believe in the person themselves, regardless of their past actions. It is believing in the human being behind the behavior, without demanding collateral or guarantees. It means separating your task—the act of trusting—from their task—how they respond to that trust.
YOUTH: But if I trust unconditionally and they betray me, I'm the one who gets hurt.
PHILOSOPHER: The decision to trust is your task. How they act is their task. If you make your happiness conditional on them meeting your expectations, you are handing them control over your well-being. But if your goal is to build a relationship of equals, then the act of trusting is its own fulfillment. Even if you are betrayed, the goal of your action—the act of trusting—has been met. The decision to trust is a demonstration of your own strength and courage, not a reflection of their worthiness.
YOUTH: So I contribute, and I trust… but what if no one notices? What if my contribution is invisible? How can I feel happy then?
PHILOSOPHER: Now we arrive at the heart of the matter. You are still seeking external validation, still operating under a principle of reward. The final step is to understand that happiness is the feeling of contribution. It is the subjective sense that ‘I am of use to someone.’ This feeling is the only reward you need, and it is entirely within your control. You do not need praise or gratitude. You only need the internal, personal conviction that you are contributing to your community of comrades.
YOUTH: My value is determined by… my own feeling?
PHILOSOPHER: Precisely. Your value is not something bestowed upon you by others. It is something you realize for yourself through the act of contribution. This is the ultimate separation of tasks. Your task is to contribute. Whether others like you or appreciate you is their task. It has nothing to do with you. Once you grasp this, you are free. You can find happiness anytime, anywhere, simply by deciding to be of use to someone.
Part 5: Choose a Life of Love
YOUTH: Contribution, trust, community… these interpersonal tasks all lead to the most daunting one of all: love. Everything you’ve said seems to apply to friendships or work, but love feels different. It’s a force of nature. You ‘fall’ into it. It’s about fate, passion, finding your other half.
PHILOSOPHER: That passive, romantic view of love is the cause of immense heartbreak. People wait for a magical feeling to strike, and when the initial passion fades, they believe the love is gone and move on, forever chasing that first high. Adlerian psychology proposes something far more radical and stable. Love is a task, not a feeling. It is not something you fall into; it is something you decide to build.
YOUTH: A decision? You’re saying love is a choice? That feels so unromantic.
PHILOSOPHER: Is it? What could be more profound than two self-reliant individuals making a conscious commitment to build a life together? The initial feeling of ‘I like this person’ is merely the starting point, the spark. True love is the decision that follows: the commitment to the life task of a relationship with another. It is an act of will.
YOUTH: What is the task, then? What does it mean to ‘build’ love?
PHILOSOPHER: It is the task of shifting the subject of your life. When you are single, the subject of your life is ‘I’. ‘I am happy.’ ‘I am sad.’ ‘What will I do?’ The task of love is to create a new, shared subject: ‘We’. The goal is no longer about fulfilling the needs of ‘I’, but about achieving the happiness of ‘We’. ‘What will make us happy?’ ‘How can we overcome this challenge?’ It is the ultimate act of cooperation and contribution.
YOUTH: From ‘I’ to ‘We’… But in doing that, don’t you lose yourself? Doesn’t the ‘I’ get sacrificed for the ‘We’?
PHILOSOPHER: On the contrary. Only a truly self-reliant person can engage in the task of love. Achieving true self-reliance does not mean isolation. It means having the ability to stand on one’s own two feet, free from the need for praise or the fear of disapproval. It means being a whole person, not a half looking to be completed. Two such self-reliant individuals can then choose to join together, not out of neediness, but out of a shared desire to build a greater happiness. They don’t lose their ‘I’; they elevate it into a ‘We’.
YOUTH: So all the previous steps… rejecting etiology, building horizontal relationships, contributing to a community… they are all preparation for this ultimate task?
PHILOSOPHER: Exactly. You cannot build a ‘We’ if you are trapped in a vertical relationship of praise and rebuke. You cannot build a ‘We’ if you see your partner as a competitor. You cannot build a ‘We’ if you are unwilling to trust unconditionally and contribute without demanding a reward. Love is the grand synthesis of all these principles.
The Youth fell silent. The words settled in the quiet room, no longer abstract theories but a clear, challenging path forward. The philosopher’s voice softened.
PHILOSOPHER: We have journeyed far tonight, from a misbehaving schoolboy to the very definition of love. In the end, they are connected. The courage to help that boy without praise or rebuke is the same courage required to build a life with another. Ultimately, the courage to be happy is the courage to love. It is the courage to commit to interpersonal relationships, to face their challenges, and to find your joy in contributing to another’s well-being. It is the courage to choose your life, to choose your fate. And the greatest fate we can choose… is to love.
The first light of dawn filtered through the window. The long night of discussion was over. The Youth looked not exhausted, but stilled, as if a great storm within him had finally passed. He stood up, his shoulders no longer slumped.
YOUTH: Thank you, Master. I have a lot to think about. And a lot to do.
PHILOSOPHER: That is all one can ever ask. Now go, and begin.
Ultimately, the book’s powerful conclusion reveals the youth’s complete transformation. After grappling with the philosopher’s teachings, he makes the courageous decision to dedicate his life to education, fully embracing Adlerian principles to guide his students. This resolution is the book's core spoiler and triumph, demonstrating that the philosophy is not just a theory but a livable practice. The final arguments cement the idea that true happiness is found in the courage to love, to see others as comrades, and to contribute to a community. This shift from self-interest to social interest, culminating in the youth's decision, is the book’s most significant takeaway. Its strength lies in making profound concepts accessible and applicable, showing a clear path to a self-determined life. We hope you enjoyed this summary.
