Stories don't usually stick around for centuries if they're just about gardening. Honestly, if you’ve spent any time on the internet or in a library lately, you’ve probably run into some version of the old man and the tree. It’s one of those "wait, I know this one" tales that feels familiar even if you can’t quite place where you first heard it. Most people think it’s just a cute story for kids about being nice to the planet. They're wrong. It’s actually a pretty brutal look at human ego, legacy, and the fact that we’re all going to die eventually.
People have been telling variations of this for ages. Sometimes it’s a Greek proverb. Sometimes it’s a Sufi teaching. Other times it’s a bit of folklore from the Levant. But the core is always the same: an old man is planting a tree that takes decades to fruit, a passerby calls him a fool, and the old man drops a truth bomb that makes the traveler feel like an idiot.
What the story of the old man and the tree is actually about
Let’s look at the most famous version, often attributed to various Middle Eastern traditions or popularized in collections of "wisdom" stories. An old man, usually in his 80s or 90s, is out in the sun digging a hole. He’s planting a carob tree. Now, carob trees are notoriously slow. In the ancient telling, they say it takes 70 years for a carob tree to bear fruit.
A younger guy walks by. He’s probably wearing the ancient equivalent of a designer suit and checking his watch. He sees the old man—hunched over, sweating, shaking—and laughs. "Hey, old timer," he says. "You’re 90. You really think you’re going to be around to eat the fruit from that tree?"
The old man doesn't even stop digging. He just looks up and says something like, "I came into a world where I ate fruit from trees I didn't plant. I’m planting this so my grandchildren can eat, too."
Boom.
That’s the hook. It’s about intergenerational debt. We live in a culture of "I want it now." We want the 15-minute delivery, the instant download, the immediate ROI. The old man and the tree is the ultimate middle finger to that mindset. It’s a reminder that most of the good things we enjoy today—public parks, stable bridges, even the languages we speak—were built by people who knew they wouldn’t see the "finished" product.
The Carob Tree Myth vs. Reality
Wait. Does it actually take 70 years?
If we’re being scientifically accurate, no. Ceratonia siliqua, the carob tree, usually starts producing pods after about 6 to 7 years. It hits full production at maybe 20 or 25 years. So, the "70 years" in the fable is a bit of a poetic exaggeration. It's used to emphasize the gap between the planter's life and the tree's maturity. In the Honi ha-M'agel story from the Talmud, the 70-year figure is central to the miracle that follows (he falls asleep and wakes up 70 years later to see the grandson eating the fruit).
But even if the math is a bit off, the sentiment holds. Planting a slow-growing hardwood or a massive oak is an act of faith. It’s a quiet admission that the world is bigger than your own lifespan.
Why we keep coming back to this story in 2026
We’re obsessed with legacy. But we usually think of legacy as "how many followers do I have" or "how much is in my 401k." The old man and the tree offers a different metric. It suggests that a life well-lived is measured by the shade you provide for people you will never meet.
The Psychology of "Deep Time"
Psychologists call this "generativity." It’s a stage of development where adults start caring more about the next generation than their own success. If you don't hit this stage, you get stuck in stagnation. You become the bitter guy wondering why nobody is thanking you for things you haven't even done yet.
The old man in the story is the "final boss" of generativity. He doesn't need the fruit. He’s already satisfied. There’s a certain kind of peace that comes from doing work that doesn't benefit you personally. It removes the stress of "is this worth it?" because the value isn't tied to your own bank account.
- It's not about the fruit.
- It's not about the praise.
- It's about the continuity of life.
Honestly, the world would be a lot less chaotic if more people thought like this. Imagine if tech CEOs or politicians actually cared about the "fruit" 70 years from now instead of the next quarterly earnings report.
Common Misconceptions about the Legend
One big mistake people make is thinking the old man is being "selfless." That’s a bit of a simplification. In many versions of the story, the old man is actually being quite practical. He knows how the world works. He understands that a society that only plants things it can eat immediately is a society that is dying.
Another misconception is that the story is strictly religious. While it’s found in Jewish, Muslim, and Christian contexts, it’s really a universal human observation. It’s about the "Long Now."
There’s also a Greek version often cited: "A society grows great when old men plant trees whose shade they know they shall never sit in." It’s a beautiful quote. The funny thing? Nobody can actually find it in ancient Greek texts. It’s likely a modern "translation" or a summary of these older fables. But does it matter? Not really. The truth of the statement doesn't change just because we can't find a specific parchment from 300 BC with that exact phrasing.

Applying the "Old Man" Logic to Modern Life
How do you actually use this? You probably aren't going out to plant a carob tree this afternoon. But the principle of the old man and the tree applies to almost everything you do that has a long tail.
Think about climate change. Or debt. Or even the way you raise your kids. If you’re only looking at the 24-hour news cycle, you’re the guy laughing at the old man. You’re the one saying, "Why bother? I won't be here."
Small Actions with Long Tails
- Mentorship: Spending three hours teaching a junior employee a skill doesn't help you finish your work today. In fact, it slows you down. But in five years, that person might lead a department. That’s a tree.
- Open Source Software: Writing code and giving it away for free. You aren't getting paid, but you're building the infrastructure for the next decade of the internet.
- Sustainable Living: Buying the more expensive, durable item instead of the cheap plastic one. You're reducing the "trash" debt the next generation has to pay.
It’s about shifting your perspective from "What do I get?" to "What remains?"
The Darker Side of the Fable
There’s a flip side to this. What happens when the "old men" plant thorns instead of trees? We’re currently living in the "shade" (or the heat) of decisions made 50 years ago. When we talk about the old man and the tree, we usually assume it’s a good tree. But the fable is a warning, too. Legacy is inevitable. You are planting something every day. Whether that's a toxic culture, a pile of debt, or a beautiful orchard is up to you.
The traveler in the story is always the one who looks foolish in the end. He represents the "short-termism" that plagues human history. He’s the one who sees a forest and only thinks about how much the lumber is worth today. The old man sees the forest and thinks about the air, the soil, and the children.
A Note on Modern Environmentalism
In 2026, this story feels more relevant than ever. With the shifts in global climate, planting a tree isn't just a metaphor anymore; it's a literal necessity. We are seeing a massive movement of "rewilding" across Europe and North America where people are doing exactly what the old man did. They are planting native species that won't reach maturity until long after the planters are gone.
It’s a rejection of the "doomer" mindset. If the old man believed the world was ending tomorrow, he wouldn't bother with the shovel. Planting the tree is an act of radical optimism. It's saying, "I believe there will be people here in 70 years, and I want them to be fed."
Actionable Steps for a Legacy Mindset
If you want to live more like the "old man" and less like the skeptical traveler, you don't need a farm. You just need a change in how you weigh your decisions.

Start by identifying one "long-term" project that offers you zero immediate benefit. This could be contributing to a community garden, starting a college fund for a nephew, or even just writing down your family history so it isn't lost.
Next, audit your "short-term" complaints. Most of the things we stress about are "traveler" problems—things that won't matter in a week, let alone 70 years. When you find yourself getting worked up, ask: "Am I worrying about the fruit, or am I focusing on the planting?"
Finally, look for ways to "pay back" the trees you're already sitting under. Someone built the road you drive on. Someone fought for the rights you exercise. Recognize that you are currently the "grandchild" in someone else's carob tree story. That realization usually breeds enough gratitude to make you want to pick up a shovel yourself.
The old man isn't a saint. He’s just someone who understands that time is a circle, not a line. He knows that as long as someone is planting, the story never really has to end.
