It's a wonderful thing to be optimistic. It keeps you healthy

Hear, O children of the mind and heart, the words of Daniel Kahneman, master of thought and weaver of insight: “It’s a wonderful thing to be optimistic. It keeps you healthy and it keeps you resilient.” In these words he does not speak only as a scholar of the human psyche, but as one who has looked deeply into the power of perspective. For optimism is no fragile dream—it is strength, a shield for the body and a fortress for the soul.

The meaning of this teaching is that the mind governs more than thought; it shapes health, endurance, and the very spirit of life. The pessimist, who lives in shadows and rehearses despair, weakens both body and will. Fear and bitterness gnaw at vitality, eroding health and destroying courage. But the optimist, who believes that tomorrow holds promise, summons a mysterious energy. Their heart beats stronger, their spirit rises higher, their endurance deepens. In optimism lies the secret of resilience—the ability to bend without breaking, to fall and rise again.

The origin of these words flows from Kahneman’s lifelong study of human behavior. He explored how the mind perceives, chooses, and endures, and he found that belief itself shapes reality. The optimist is not blind to hardship, but sees beyond it, finding pathways where others see only walls. Kahneman reminds us that optimism is not mere foolish cheer—it is a force that sustains health and fuels perseverance in the trials of life.

Consider the story of Winston Churchill, who in the darkest days of war refused to let despair rule his spirit. While bombs fell upon London, he spoke with fiery conviction: “We shall never surrender.” His optimism was not naive; he knew the cost of war. Yet by holding fast to hope, he gave his people the strength to endure. That spirit kept them resilient, and their courage outlasted the storm. His words and vision stand as testimony to the life-giving power of optimism.

Think also of Helen Keller, who was left deaf and blind from childhood. She could have surrendered to despair, yet she chose hope. With optimism, she embraced learning, touched the world through her writings, and became a beacon for the disabled everywhere. Her health and spirit endured not because her life was easy, but because she chose to see the unseen light. Her life proves Kahneman’s wisdom: optimism keeps the soul alive, even when the body suffers loss.

O seekers of tomorrow, understand this: resilience is not born of strength alone, but of vision. The soldier who believes he will prevail fights longer; the patient who believes she will recover heals faster; the worker who believes in the fruit of his labor toils with greater joy. To be optimistic is not to deny pain—it is to declare that pain shall not be the end. And in that declaration lies the secret of vitality.

Practical wisdom calls you: each morning, choose to frame your day with hope. Speak words of encouragement, first to yourself and then to others. When obstacles arise, do not say, “This is the end,” but ask, “What lesson or path lies hidden here?” Surround yourself with hopeful voices and avoid the poison of constant negativity. In this way, you will preserve your health, fortify your spirit, and cultivate resilience in the face of life’s storms.

Therefore, remember the teaching of Daniel Kahneman: “It’s a wonderful thing to be optimistic. It keeps you healthy and it keeps you resilient.” Hold it close as a shield. For health and strength are not found in despair, but in the steady gaze of hope. Walk with optimism, and though trials may come, you shall endure them with spirit unbroken, rising again and again until victory is yours.
