It often feels as though our existence is nothing more than a brief visit—a passing journey, as Fairuz so poignantly expressed: “we came to this life only for a short journey.” This simple idea carries a profound weight. After a lifetime that has stretched across decades—nearly a century—I find myself returning to the same question: what have I truly done, and what will remain after I am gone? I have lived, worked, produced, and achieved. I have engaged with people, contributed to my field, and carried dreams—many dreams—of a better, fairer world. Yet when I place all of this against the vast scale of existence, it begins to feel like a fleeting moment, almost imperceptible in the grand timeline of the universe.

What is the measure of a human life? Is it the years we accumulate, the work we produce, or the legacy we believe we leave behind? On a cosmic scale, our presence is less than an instant—a fraction of a moment. And yet within this brief interval, we carry immense questions: Are we truly living, or merely passing through? Is our purpose to build, to compete, to dominate, or simply to witness? Humanity, throughout its history, has oscillated between creation and destruction. We have built civilizations, advanced knowledge, and shaped cultures, but we have also waged wars, oppressed one another, and pursued power with relentless determination.
It is difficult to ignore the possibility that within each of us lies a contradiction—a capacity for both good and evil, for compassion and cruelty. Perhaps what drives history forward is not only our aspiration toward progress, but also an inner tension that we struggle to contain. From ancient conflicts between tribes to modern wars between nations, from the earliest tools of survival to the most advanced weapons of destruction, the pattern remains strikingly consistent. The forms change—today we speak of technology, wealth, and even artificial intelligence—but the underlying impulses often remain the same.
We speak frequently of success. We celebrate those who excel in knowledge, accumulate wealth, or achieve influence. But success, in many ways, is relative. Better than whom? Greater than what? Are we advancing toward something meaningful, or simply outpacing one another in an endless race? Education, work, ambition—these are all framed as pathways to a “better life.” Yet this notion of “better” is often defined in comparison, rooted in competition rather than collective well-being.
As I reflect on nearly a lifetime of experience, I am confronted not with certainty, but with humility. I have learned much, observed much, and participated in the world as best I could. And yet, I find myself admitting that I do not fully understand where we are going. The future of humanity remains uncertain. Will we evolve beyond our destructive tendencies, or will we simply refine them through more sophisticated means? Power itself has transformed over time—from physical strength to weaponry, from economic dominance to technological control. Today, new forces emerge, raising questions not only about progress, but about who holds influence over the direction of our shared future.
And so the question persists: what remains? What do we truly leave behind? Are “good deeds” inherently good, or are they shaped by the same systems of power and perception that define success? Even the virtues we celebrate may be intertwined with strength, influence, and context. In the end, everything we build—institutions, achievements, reputations—exists within the boundaries of time. And time, inevitably, dissolves all things.
Perhaps the most honest conclusion is also the simplest: our presence here is temporary. A brief visit. A passing moment. We arrive, we strive, we question, and we leave. After all the learning, all the effort, and all the accumulation of knowledge and experience, I am left with a quiet realization—I do not know as much as I once believed. I do not know where humanity is ultimately headed, nor how long this journey will last. But I do know that, in the vastness of existence, our lives—no matter how long or full—remain a fleeting stop in an endless continuum.
