Growing up is a trap. At least, that’s what a lot of people feel lately. You see it in the thirty-somethings living in basement apartments, not because they’re broke, but because they can’t decide what they want to be when they "grow up." You see it in the "Peter Pan" syndrome of men who refuse to commit to a relationship, a career, or even a lease.
In psychology, we call this the puer aeternus.
It’s a Latin term that basically translates to "eternal boy." While it sounds sort of whimsical—like a Neverland fantasy—the reality is a lot grittier and more depressing. It’s a state of arrested development that leaves people feeling like they’re perpetually standing in a waiting room, waiting for their real life to begin while the clock aggressively ticks toward middle age.
What the Puer Aeternus Problem Actually Looks Like
Marie-Louise von Franz, a heavyweight in the world of Jungian psychology, literally wrote the book on this. She was a close associate of Carl Jung and spent years dissecting why some people just... don't mature.
She wasn't just talking about guys who play too many video games.
It’s deeper. The puer aeternus feels a strange sense of superiority over "ordinary" life. To them, the mundane reality of a 9-to-5 job, paying taxes, and choosing a lawnmower feels like a death sentence. They’re always looking for the "extraordinary." This leads to a life that feels provisional. It's like they're living a dress rehearsal. They think, "I’ll take this job for now, but it’s not who I really am." Or, "I’m dating this person, but I’m keeping my eyes open for the 'one'."
Eventually, you wake up at 45 and realize you’ve never actually started.
The Mother Complex and the "Glass Ceiling" of Maturity
You can't talk about the puer without talking about the mother. Jungians argue that this condition is almost always rooted in an intense, often suffocating, bond with the mother figure.
It’s not always "overbearing" in the way we think. Sometimes it’s a mother who was too "perfect," making the real world seem cold and harsh by comparison. The son (or daughter, the puella aeterna) remains psychologically tied to the womb. They want the warmth. They want the lack of responsibility.
The result? A terrifying fear of boundaries.

Boundaries feel like a cage. To the puer, making a choice—any choice—means killing off all other possibilities. If I choose to be a carpenter, I can no longer be an astronaut, a rockstar, or a diplomat. So, they choose nothing. They stay "full of potential." But as Von Franz pointed out, potential that isn't realized is just a fancy word for "nothing."
The Dangerous Allure of "Staying Young"
Honestly, our current culture is a breeding ground for this. We worship youth. We’re told to "follow our passion" and "never settle."
This is great advice if you’re eighteen. It’s a disaster if you’re thirty-eight.
The puer aeternus problem manifests as a constant need for intensity. These individuals often gravitate toward "highs"—extreme sports, new romances, or constant travel. Anything to avoid the "boredom" of a Tuesday afternoon. But life is mostly Tuesday afternoons.
If you can’t handle a Tuesday, you can’t handle life.
The Puer in the Workplace
In a professional setting, these folks are often brilliant. They’re the "idea people." They come in with a visionary plan that’s going to disrupt the entire industry. They’re charismatic. They’re energetic.
Then, the actual work starts.
The moment things get repetitive or difficult, the puer loses interest. They feel "misunderstood" or "stifled" by the corporate structure. They quit. Or they get fired. Then they move on to the next big thing, convinced that this time it will be different. This cycle can repeat for decades. It’s a trail of half-finished novels, abandoned startups, and "consulting" gigs that never quite materialized.
Is There a Cure? (The "Work" Nobody Wants to Do)
Von Franz was pretty blunt about the solution. She said there is only one way out of the puer aeternus trap:

Work.
Not "meaningful" work. Not "passionate" work. Just... work.
Specifically, mundane, repetitive, "earthy" labor. The kind of work that requires you to show up when you don’t feel like it. The kind of work that has no immediate payoff. Jung himself used to do stone masonry. He’d go out and physically move rocks. Why? Because it grounds the ego. It forces the "eternal boy" out of the clouds and back onto the dirt.
It’s about commitment.
Breaking the Provisional Life
The hardest step for someone struggling with this is making a "final" decision.
- Commit to a location. Stop looking at Zillow in other cities. Stay where you are for three years.
- Commit to a person. Realize that "the one" is a myth designed to keep you from the hard work of a real relationship.
- Commit to a craft. Pick something and get good at it, even the parts that suck.
It feels like dying. To the puer, commitment feels like the end of their freedom. But the irony is that they aren't free anyway. They're slaves to their own whims and the "provisional" nature of their existence. True freedom only comes after you’ve built a foundation. You can’t build a house on a cloud.
The Role of Modern Technology
We have to admit that the internet has made the puer aeternus problem a billion times worse.
Think about it.
Social media allows us to curate a "potential" life. We can look like we’re living the dream without actually doing the work. We can jump from one hobby to another with the click of a button. We have infinite options for dating, for careers, for entertainment.

This "infinite choice" is the puer's greatest enemy. It feeds the delusion that you never have to choose. You can just keep swiping. You can just keep scrolling. You can stay in the "waiting room" forever because the waiting room is actually pretty comfortable now. It has Wi-Fi and DoorDash.
Acknowledging the Nuance: Is Being a Puer Always Bad?
It’s easy to bash the "man-child" or the "eternal girl." But Jungian psychology isn't about shaming.
The puer archetype has a positive side. These are the creators, the dreamers, and the people who keep the world from becoming a grey, bureaucratic nightmare. We need the "divine youth" energy. We need the ability to see things with fresh eyes and to question why things are the way they are.
The goal isn't to kill the puer. It's to integrate him.
You want to keep the creativity and the spirit of the youth, but you need to give him the skeleton of an adult. An adult who can handle a spreadsheet. An adult who can apologize when they’re wrong. An adult who stays when things get boring.
The Turning Point: The "Midlife" Crisis
For many, the realization hits in their late thirties or early forties. The "mirrored" life—the one where you see yourself as a hero in a movie that hasn't started filming yet—shatters.
This is often a period of deep depression.
You realize you aren't a "young prodigy" anymore. You’re just a middle-aged person who hasn't accomplished much. This is the "nadir," the lowest point. But in psychology, this is also the place where real growth happens. It’s the moment you finally stop waiting for your life to start and realize that it’s been happening the whole time.
Actionable Steps for Transitioning Out of the Puer State
If you suspect you’re stuck in a "provisional life," you don't need a massive life overhaul. You need small, boring habits that tether you to reality.
- Establish a "Non-Negotiable" Routine: Pick three things you do every single day, regardless of your mood. This could be as simple as making the bed, walking for 20 minutes, or writing 500 words. The goal is to prove to yourself that your whims don't control your actions.
- Limit "Novelty Seeking": If you find yourself constantly starting new hobbies or looking for the "next big thing," force yourself to stick with your current project for six months. Even if you hate it. Especially if you hate it.
- Physical Labor: Find a way to work with your hands. Garden, fix a bike, learn to cook a complex meal from scratch. Engaging the physical body is the quickest way to ground a flighty intellect.
- Financial Autonomy: If you’re still relying on parents or others for financial support in your 30s, making a plan to cut that cord is the single most important thing you can do. Dependency is the fuel for the puer aeternus.
- Voluntary Sacrifice: Choose something to give up. Sacrifice some of your "freedom" for the sake of a community, a partner, or a long-term goal. Realize that every "yes" requires a thousand "nos."
The transition from puer to adult isn't a single event. It's a daily choice to accept the limitations of being human. It's about realizing that a "small" life lived fully is infinitely better than a "great" life that only exists in your head. Stop waiting for the perfect moment. It isn't coming. Pick up the stones and start building.
