How to Read “Desire your courage to be large, desire your heart to be small”
Kimo wa dai naran koto wo hosshi, kokoro wa shō naran koto wo hossu
Meaning of “Desire your courage to be large, desire your heart to be small”
This proverb teaches that you should have great courage while maintaining careful attention to detail. When making big decisions or taking action, you should act boldly without fear.
At the same time, you should be thoughtful and considerate in small matters. Both qualities are essential.
People use this saying when talking to leaders or those facing important decisions. It emphasizes balancing brave challenges toward big goals with careful attention to those around you.
In modern times, this applies especially to business and organizational leadership. The best leaders combine both qualities.
Bold decision-making alone is not enough. Careful consideration alone is also insufficient. True leadership power comes from having both.
Origin and Etymology
This proverb likely comes from ancient Chinese philosophy. Using contrasting concepts like “gallbladder” and “heart” to describe the ideal person was common in Chinese military texts and philosophical writings.
The word “gallbladder” has long symbolized courage and bravery. Terms like “gallbladder power” and “gallbladder wisdom” show how this organ represented strength in facing challenges.
Meanwhile, “heart” was understood as the source of careful consideration and thoughtfulness.
By contrasting these two with “desire to be large” and “desire to be small,” the proverb teaches something important. It shows that seemingly contradictory qualities can exist together.
Boldness and delicacy, courage and caution—having both opposing traits makes a truly excellent person.
Chinese philosophy and military strategy came to Japan long ago. Warriors valued these teachings as essential knowledge.
This proverb became established in Japan through such cultural exchange. It has been passed down as guidance for leadership and character development.
The importance of combining action courage with attention to detail resonates across generations. This teaching continues to touch people’s hearts today.

Universal Wisdom
This proverb has endured because it addresses one of human growth’s most difficult challenges. We tend to lean too far in one direction.
When we try to be bold, we become careless. When we try to be careful, we become timid. This contradiction is humanity’s eternal struggle.
Looking back through history, truly great achievers all possessed both qualities. They held big visions that inspired people while listening to each individual voice.
They had courage to face difficulties while maintaining alertness to small warning signs. Integrating these contradictory qualities shows the measure of a person’s character.
Why do people strive for this way of living? Because we instinctively understand that true strength isn’t just raw power.
Real strength includes flexibility. Bamboo survives strong winds because it bends. Humans too can weather life’s storms by combining boldness with sensitivity.
Our ancestors condensed this human ideal into simple words. They showed us the path forward.
When AI Hears This
Control engineering uses a concept called “gain” to stabilize systems. This number shows how strongly a system reacts to input signals.
Interestingly, optimal control systems need completely opposite gain settings for large external changes versus small internal noise.
Consider a self-driving car. For major external threats like sudden pedestrians or weather changes, you need high gain—quick, bold steering adjustments.
But for internal noise like tiny sensor errors or slight engine vibrations, you need low gain. Delicate responses prevent the whole system from becoming unstable. This is called “robust control.”
Mathematics proves that disturbance rejection and internal stability have a trade-off relationship. Increase external responsiveness too much, and internal stability suffers.
Worry too much about internal details, and external response becomes sluggish. The optimal solution uses both gains appropriately.
This ancient proverb expressed the essence of control theory through experience, without equations. Boldness and delicacy aren’t contradictions.
They’re both essential conditions for creating stable systems.
Lessons for Today
This proverb shows modern people how to escape the perfectionism trap. We often fall into extremes—either too cautious to act, or rushing forward recklessly to failure.
What we really need is wisdom to use both qualities depending on the situation.
When you challenge something new, first you need courage to take a big step. If you wait for perfect preparation, opportunity never comes.
At the same time, after you start moving, stay sensitive to reactions and small changes around you. Hints for course correction always hide in the details.
This teaching matters especially in our social media age. Have courage to boldly express your opinions, but don’t forget consideration for others.
Move toward big goals, but don’t miss daily small joys. This sense of balance becomes the key to building a fulfilling life.
Trust both the boldness and delicacy within you. Take that first step forward.
