Some people reach this point early on in their lives, and others very late. Some people only reach it after undergoing a difficult period and still others reach it with very little drama or pain. I didn't personally come to this realization until I hit my "rock bottom". People never stop feeling sorry for you, but eventually, everyone stops trying to help. When it clicked, though, it changed my life. I've never been the same since, and I believe that's because I made the transition from being a child to becoming an adult.
The reason I say that is I've know individuals who have taken the first mantra to mean that they hold no responsibilities to other people. That it is, in a reductio ad absurdum, that a driver has no responsibility to stay off the sidewalk and that the onus should lie entirely on the pedestrians to dodge her vehicle.
My great-grandfather left his home at the age of 12 to work in a coal mine and send money home to his mother. I'd say he was as much an adult as any college grad today.
My wife's grandpa managed a dairy farm. He got sick once when my wife's dad was 10 years old. Her dad milked the cows so her grandpa could rest and get over his illness. He hasn't stopped milking cows twice a day for 50 years. I'd say he was an adult at 10.
My dad was taught to work like a man from an early age, but was also taught to drink to excess. I remember when he got his last DUI. I was about 11 years old. I'd say that was when he finished growing up.
The dividing line between childhood and adulthood for me is a total blur between the ages of 18 and 28.
I don't think this definition fits extended family cultures like you'd see in other parts of the world very well.
As a child we generally assume everyone "above" us knows what they're talking about. Authority derives from behind the curtain that is defined by a hope that whomever is leading us knows what the hell they're doing. And suddenly, when we realize that they don't - that we're all lost - we can start forming our own vision of the world as we would prefer to see it.
That, along with ownership of the personal responsibility you mentioned, defines the difference between childhood and coming into ones own. I think the two are complimentary and I don't believe either revelation exists without the other.
That's when the buck really stops, forget the bills and all the rest.
I don't becoming an adult is really about you, exactly. It's not about your independence, or your actions.
It's about when other people become dependent on you.
I think this is the way that it has long been thought of in cultures outside of the post-Enlightenment West. This was my strong opinion after reading Dostoyevsky, Tolstoy, (Russia isn't western like the rest of Europe) and Aquinas, Augustine, and Aristotle. I think that this is in part what the Apostle Paul is saying in 1 Corinithians 13:11 ( http://www.esvbible.org/1+Corinthians+13%3A11/ ), where you'll note that he doesn't say the equivalent of stopping to be like a child meant I had become a man, but rather I became a man, so I stopped being like a child.
I think about soldiers I have met and know. They change when they get to NCO status. I think of the boys I have met from North Omaha, which is arguably one of the worst places in America for young African American males, and that there is a difference between the ones who are the oldest in their families and the ones who are the youngest, even if they are the same age. And I think of my friends, and how we've changed when we've had kids, or when someone started a business and got ( real, not just one of his buddies-while-still-in-high-school ) employees.
Adulthood isn't about you, it's about your relationship to others.
...and I've never felt like an adult. I can have the weird dichotomy of having friends young enough to have missed everything I relate to my childhood, friends that I consider "adult", and yet I still feel like I did when I graduated college.
I have talked with CEOs and VPs or just other coders that are younger than I, yet I "feel" like they are older, more experienced.
I have no idea when I'm really an adult, but I don't expect it will be soon.
For me it was when I got married. At first it was like cool and then it dawned on me that as head of household, I was responsible for more than just ME!
Once my kids were born, a different type of adulthood settled in. The decisions that I had made earlier in my life about things like moving, finances, and doing stupid things on the weekends with my wife weren't as easy to make or not even possible.
And now as time has passed, I've had to deal with aging parents. I now talk with my mom and dad as an adult and not a child. Our discussions when dealing with serious topics related to health or family now weigh heavier on me. I now carry a sense of responsibility with me that I just can't shake.
For me the moment I entered adulthood was the moment I couldn't shake my responsibilities anymore. I also want to point out that I choose to be responsible. Could I decide tomorrow to be irresponsible? Hell yes, but I choose not to because I have people that depend on me.
One last thing, being an adult does not stop me from doing kid like things. I still play plenty of video games like my favorite Black OPS 3 (many hours have been thrown into that black hole of time) and watch cartoons like Bleach (soap opera for nerds).
My two cents worth.
So when we're saying "are you an adult?" I'd like to ask what are we REALLY getting at. An ability to handle X class of situations? An ability to make X levels of abstract reasoning about social processes? There are so many and so variable a set of objective and subjective markers that any sort of broad statement seems useless, at best, deceptive and detracting from the actual markers at worst.
I had a conversation with my father once, something along the lines of, "We really all just get better at pretending, don't we?"
I'm not sure what my "Central point" of this post is, (and it's far from my more rigorously argued ones) so take it as a collection of thoughts on how I've found the most "personal enlightenment" regarding adulthood, as a rather transparent contrived construct; realizing this was (perhaps ironically given my thesis on this) my internal moment of "I have reached adulthood".
In this mode, there is little time or urge for compassion, or play, or joy. You are a cog in a large machine that values you only and precisely according to your economic function, who's body participates in multiple overlapping patterns of decay, and that's it. Maybe, if you're religious, you can look forward to a happy afterlife (and indeed one can imagine the role of religion in such a person's life is to offer a reason to not act out on the rage that inevitably underlies such an existence).
Almost everyone on HN is lucky to not have to endure this (or at least, for any length of time). And indeed, startups cannot succeed with that grimness. You must maintain your sense of play and joy, I think, to be successful in this space, because this is the most playful and joyful part of the economy! We make stuff that makes people go "ooh" and "ahh", and how can you really do that if you're an adult?
There is a transition when people stop caring for you and you care for yourself but for no one else yet. We call this teens.
Call it what you want, it's not really age dependant. We have simply put words on psychological changes and tied them with age.
Some people become adults at 12 years old. Other at 40. I've met "adults" that are only tall children and children that are short adults.
The whole topic is centered around Adulthood is a social construct. For that matter, so is childhood. And, at some level, you should realize the classification is, well, hogwash.
I first drove a truck when I was 11. My dad drove tractor all summer starting when he was 9. The 3 year old in Dune killed dying enemy soldiers when 3. These are all presumably adult activities. I substantially took care of a farm at the age of 12.
If you are lucky enough to figure out who you are at a young age, the rest is semi-interesting narrative.
Forget the classifications that others would impose on you. Do what you love, and the rest will sort itself out.
I once had the following conversation with my daughter, i think when she was 15. I said, a bit tongue in cheek, "Be patient with your parents, as they are only now catching up to the notion of who you are, or were, and know they will know no more about you or your life than you did when you were six." She gave a silent smile.
Notice that this has nothing to do with style, fashion, or entertainment choices. You can drink scotch, smoke cigars, wear suits every day, and drive a luxury automobile, that doesn't make you more mature. And you can chew bubblegum, watch cartoons, play videogames, wear jeans and hoodies, that doesn't make you less mature.
Beyond that, I think as an adult it's a critical moment to realize it's not about what you get from the world, but what you are able to give, and your ability to think about others as much as you think for your self is critical when you have to work and function with any combination of working in the world, relationships, family and kids.
That is, you've managed your own affairs so that you're now in a position to help others who need help managing theirs...
That's the cornerstone of a healthy and productive society--accomplished elders mentoring the young on a consistent basis...
I didn't consider making a baby adulthood, or getting a $100k/year job to be adulthood. If anything, I was _less_ responsible for my own actions (ballooning to 360lbs), because I started focusing on the things I _had_ to do, and let my personal development stop due to not having time.
Oddly, I realized and _grasped_ the concept that I had to take responsibility for my actions at around 19. But thinking that I had to check these checkboxes off my "Steps to Adulthood" list, I put off everything else in order to achieve it. I didn't actually achieve adulthood from that path, I just had the trappings and appearance of adulthood. But I was still about 13 years old inside.
I didn't consider myself an adult until the second time I made a judge run out of the courtroom (I declared a de jure court mid-sentencing after serving him notice of that right). The actual reason is less than relevant, but it was the taking control of my potential, and using it responsibly to help someone else, that brought me to adulthood.
The real Thoreau was, in the fullest sense of the word,
self-obsessed: narcissistic, fanatical about
self-control, adamant that he required nothing beyond
himself to understand and thrive in the world.

“Walden” is less a cornerstone work of environmental
literature than the original cabin porn: a fantasy about
rustic life divorced from the reality of living in the
woods, and, especially, a fantasy about escaping the
entanglements and responsibilities of living among other
people.
Much of which, as many here argue, is essential to 'being an adult'.This may be anecdotal, but I've found a very strong association between age and maturity in my life, especially under 25. If you were to do a blind chat with a 10, 15, 20 and 25 year old do you really believe you wouldn't be able to place them accordingly?
But maybe this is just my own biases deluding me. I'd like to think I'm a better man than I was 5 years ago, and will continue to be a better one 5 years in the future. Then again, is maturity really defined as being "a better (wo)man", because according to dictionary.com it's defined by age.
Either way I'd be curious for that professor's full quote. Maybe if we could replace "[maturity]" with what she actually said it would shed some insight on what exactly we're talking about.
EDIT; key sentence below:
> Over the course of his research on this, Jensen Arnett has zeroed in on what he calls “the Big Three” criteria for becoming an adult, the things people rank as what they most need to be a grown-up: taking responsibility for yourself, making independent decisions, and becoming financially independent.
I can't say I definitively crossed the threshold of adulthood that day, but the kid in me grieved. He was no longer in control... of everything ;) There was now a "grown-up" in charge.
"Adult plasticity still allows for modifications to the brain, but at that point, the neural structures aren’t going to change."
The above changes to neuroplasticity really hit me hard when I restarted college in my 30s.
Despite "passing" for a 20some student, I realized I learned differently than my younger colleagues.
I had to rely on association with my previous knowledge quite a bit more.
Learning something completely new became near impossible hill to climb.
That can come from (examples):
1. Becoming a parent (most people) 2. Becoming an employer (who's employees depend on you and the business for their livelyhood) 3. Other examples that you can come up with
At the point that your actions, decisions, the way you present yourself, how you spend money, etc have consequences for more than just you is the point where you really grow up.
When it's all about you, you don't really have responsibilities you just have stuff to do.
In many cultures, after an arbitrary rite of passage, children are considered "adults".
I think, personally, the point at which one becomes an adult is acknowledging the bitter and harsh truth of reality. In some sense, it may be better to remain a child forever, ignorantly blissful.
When you become your own mother and father in the sense that you supply for yourself the sense of judgment, responsibility, and diligence you first got from your parents.
