Ever notice how some 70-year-olds can hold court at any dinner party with genuine insights that make everyone lean in, while others just recycle the same tired talking points from 1987? I used to think this difference came down to life experience. More experiences equals more wisdom, right? Wrong. Dead wrong, actually.

The real difference? Whether someone spent their decades questioning their assumptions or just collecting evidence to support what they already believed.

The comfort trap of being “right”

Here’s something that might sting a little: most of us spend our lives building fortresses around our beliefs rather than bridges to new understanding. We read books that confirm what we think. We watch news that aligns with our politics. We hang out with people who nod along to our opinions.

And you know what? It feels fantastic. There’s this warm, fuzzy validation that comes from having your worldview confirmed over and over again. It’s like intellectual comfort food.

But comfort food doesn’t make you grow. It just makes you soft.

I found my old diary from my twenties recently, and let me tell you, reading it was like meeting a stranger who happened to share my name. The certainty I had about everything back then was breathtaking. And embarrassing. I knew exactly how the world worked, what was right and wrong, who deserved what. Twenty-five-year-old me had it all figured out.

Fifty years later, I know far less for certain, and that’s precisely why I understand so much more.

When life forces your hand

Sometimes the universe has a way of cracking open our carefully constructed belief systems whether we like it or not. For me, that moment came when my daughter announced she was marrying someone outside our race.

I’d always considered myself open-minded. Progressive, even. But when it became personal, when it was my daughter, I discovered biases I didn’t know existed. They bubbled up from places I’d never examined. The discomfort I felt revealed truths about myself that no amount of self-congratulation about my tolerance could have uncovered.

You want to know what real growth feels like? It feels like discomfort. It feels like your stomach dropping when you realize you’ve been wrong about something fundamental. It feels like apologizing to your daughter and asking her to help you understand.

The courage to be a beginner again

At 61, I started learning Spanish. Not for a vacation or because I had to, but because my son-in-law’s family primarily spoke Spanish, and I wanted to really know them, not just smile and nod at family gatherings.

Have you ever tried learning a new language in your sixties? It’s humbling in ways you can’t imagine. You sound like a toddler. Teenagers correct your pronunciation. You mix up words and accidentally tell someone their mother is a bicycle instead of saying she’s beautiful.

But here’s what else happens: your brain literally creates new neural pathways. You start thinking in different patterns. You realize that some concepts exist in Spanish that don’t translate to English, which means there are entire ways of understanding the world you’ve been missing.

The same thing happened when I joined a book club where I’m the only man. Every month, I sit with eight women and discuss literature, and every month, they point out themes and perspectives I completely missed. Things that seem obvious to them are revelations to me.

The veteran who changed everything

A few months back, I was grabbing coffee downtown when a homeless veteran asked if I could spare some change. My automatic response was already forming, the one we all have ready about not having cash, when something made me stop.

Instead, I asked if he wanted to share my table and have a coffee. We talked for an hour. This man had a master’s degree. He’d led troops in combat. He told me about the series of events that led him to the streets, none of which involved the lazy stereotypes I’d unconsciously believed about homeless people.

That conversation shattered assumptions I’d held for decades. Not because he convinced me of anything, but because he was just a person with a story that didn’t fit my neat categories.

How many perspectives have I dismissed over the years because they came from someone I’d already categorized and filed away?

The difference between experience and wisdom

Experience is what happens to you. Wisdom is what you do with what happens to you. And if what you do is use every experience to confirm what you already believe, you’re not gaining wisdom. You’re just becoming a more entrenched version of your younger self.

Think about the wisest person you know. Are they the one who’s always certain, always has the answer, never changes their mind? Or are they the one who listens more than they talk, asks questions that make you think, and occasionally says those three magical words: “I don’t know”?

The people who radiate opinions in their seventies are still defending the fortress they built in their thirties. They’ve spent forty years collecting ammunition for the same arguments. They can tell you why they’re right with forty years’ worth of examples, but they can’t tell you what it’s like to be wrong and grow from it.

How to choose growth over comfort

So how do we avoid becoming one of those people who confuses stubbornness with principle? Start by seeking out discomfort. Read books by authors you disagree with. Have lunch with someone from a different generation, culture, or political party. Learn something that makes you feel stupid.

When you feel that defensive wall going up because someone’s challenging your beliefs, lean into it instead of away from it. Ask yourself: what if they’re right? What if I’m missing something? What would that mean?

This doesn’t mean abandoning all your values or becoming wishy-washy about everything. It means holding your beliefs with open hands instead of clenched fists. It means being more committed to growth than to being right.

Final thoughts

The choice between radiating wisdom or opinions isn’t made in your seventies. It’s made every day in the small decisions to either protect what you believe or test it. Every conversation, every book, every new experience is an opportunity to either confirm your biases or challenge them.

I wrote once about the importance of staying curious as we age, and this is exactly what I meant. Wisdom isn’t about knowing more as you get older. It’s about being willing to know differently.

The question isn’t whether you’ll have experiences over the next twenty years. You will. The question is whether those experiences will change you or just calcify you. Choose wisely. Your seventy-year-old self is counting on it.
