I completely agree with this statement. Good deeds—such as helping someone in need, being honest, showing kindness, or standing up for what is right—create an impact that lasts far beyond material achievements. Unlike wealth or status, which can be lost due to circumstances, the respect and goodwill earned through moral actions become a permanent part of one's legacy.
In personal experience, I have seen how people who consistently act with integrity are trusted and remembered positively—even in their absence. A classmate once helped another during an exam panic attack, not for any reward but purely out of concern. That small act brought them lifelong friendship and admiration. Similarly, a teacher who treats students fairly and uplifts them is always honored—even decades later.
Doing good builds inner strength and peace of mind. It is the only treasure that grows when shared and travels with a person in reputation, memory, and self-worth.
