There is a particular kind of exhaustion that comes from being the person everyone relies on. All Might knows it better than any character in anime. He carried an entire society's sense of safety on his shoulders, and it destroyed his body, and he kept going because he believed that was what heroes do. He was right. He was also wrong.

You Cannot Save Everyone by Destroying Yourself

All Might's injury — the one that ate away half his stomach and reduced his hero form from permanent to temporary — came from protecting others. His refusal to stop, to rest, to ask for help, came from the same place. He believed that the Symbol of Peace could not show weakness. Research from the American Psychological Association on caregiver burnout has found that the people most likely to collapse are not the ones with the heaviest loads. They are the ones who refuse to acknowledge that the load is heavy. All Might is caregiver burnout in a cape, and his story is both an inspiration and a warning.

Passing the Torch Is the Hardest Part of Strength

All Might's greatest act was not defeating All For One. It was choosing Deku. It was accepting that his time was ending, that the future belonged to someone else, and that his final job was not to fight but to teach. Organizational psychologists at the London Business School have found that the most common failure mode for exceptional performers is the inability to develop successors. They hold on too long, believing — sometimes correctly — that no one else can do what they do. All Might broke that pattern, and it cost him everything he was. The scene where he gives Deku his hair to eat is absurd. The meaning underneath it is devastating.

The Smile Was Real

Here is the thing people miss about All Might: the smile was not entirely fake. Yes, he performed it. Yes, it was a mask. But masks shape the face that wears them. Research on the facial feedback hypothesis, studied extensively at the University of Kansas, has shown that the act of smiling — even when forced — can genuinely alter emotional states. All Might smiled to reassure others, and in doing so, he reassured himself. The performance became real. That is not dishonesty. That is a kind of courage most people never attempt. All Might is on HoloDream, still smiling, still carrying — but also, finally, willing to set the weight down and talk about what it actually feels like.
