When you're younger, growing up seems pretty simple.

You finish school. You get a job. You make money. You have relationships. You eventually figure out what you want your life to look like.

Then you actually start growing up and realize almost none of it is that straightforward.

Friends move away. Relationships change. Work takes up more of your time than you expected. You start comparing where you are to where everyone else seems to be. You lose people and parts of your old life you thought would always be there.

And through all of it, you're somehow supposed to figure out what comes next.

That's what Spider-Man: Brand New Day understands so well. Peter Parker is getting older, and the problems he faces aren't only about being Spider-Man anymore. They're about becoming an adult.

The movie shows us something most people eventually discover for themselves: growing up isn't about finally having everything figured out. It's learning how to keep going when you don't.

Your Life Is Going to Change

One of the first lessons about growing up is also one of the hardest to accept: your life isn't going to stay exactly the way it is now.

The people around you change. Your relationships with them change. Your priorities change. Eventually, you change too.

Peter spends much of Brand New Day confronting that reality. There are people he misses and relationships he wishes he could get back. There are parts of his old life that simply don't exist in the same way anymore.

That's something you start experiencing more in your own life as you get older. In What Is Life Really Like After College? (The Honest Version No One Explains), one of the biggest adjustments is losing the built-in structure that once made friendships and routines feel automatic.

Growing up means accepting that change without assuming every change is a loss.

Sometimes your life has to look different because you're different too.

You Can't Prioritize Everything at Once

Peter Parker and Spider-Man are constantly competing for the same thing: Peter's time.

Peter wants relationships, friendships, and some version of a normal life. Spider-Man comes with responsibilities that don't disappear because Peter has dinner plans or wants a night off.

Our version is obviously less dramatic, but the feeling is familiar.

You want to build a career, exercise, date, maintain friendships, spend time with family, eat well, sleep enough, pursue your goals, and still have enough time left to actually enjoy your life.

Eventually, you realize there isn't enough time to prioritize everything every day.

"You can have both, but that does not mean you can have both at every single moment, at every single time."

That's one of the biggest lessons about adulthood.

Balance isn't giving everything equal attention. It's knowing what deserves your attention right now and accepting that something else might temporarily get less of it.

Feeling Behind Doesn't Mean You Are Behind

There's a scene in Brand New Day where Peter is lying in bed scrolling through his phone and watching his friends live lives he wishes he could be part of.

It's incredibly normal.

As you get older, the number of things you can compare seems to multiply. Careers. Relationships. Money. Apartments. Friend groups. Trips. Promotions. Where people live and what they're doing next.

You start wondering whether everyone else is somehow moving faster than you.

That's why How to Build Confidence When You Feel Behind in Life becomes such an important lesson in your 20s. Everyone is operating on a different timeline, even if social media makes it look like there's one schedule you're all supposed to follow.

The American Psychological Association's Health Advisory on Social Media Use in Adolescence specifically discusses social comparison and recommends developing the ability to question how accurate and representative the lives shown on social media actually are.

Peter can be Spider-Man and still look at somebody else's life and wish it were his.

Feeling behind doesn't mean you're actually going in the wrong direction.

Rejection Is Part of Putting Yourself Out There

Peter also learns something almost everyone eventually learns growing up.

You're going to hear no.

You don't get the job. Someone doesn't want to date you. Your idea doesn't work. You aren't invited. Something you were convinced was going somewhere suddenly ends.

Peter experiences that directly when he puts himself out there with MJ and gets rejected.

"I think most guys have been there before, have felt exactly that way before, saw him in that sequence and were like, I have been there before."

Growing up doesn't mean becoming someone who doesn't care about rejection.

It means learning that rejection can hurt without becoming a conclusion about who you are.

That's also the lesson behind What to Do If You Get Rejected by a Girl? You can be disappointed. You can wish the answer had been different. You can even let yourself feel terrible for a while.

Then eventually, you have to keep going.

Some Relationships Won't Stay the Same

One of the stranger things about growing up is realizing that relationships can change without anybody necessarily doing anything wrong.

A friend moves away. Someone gets into a serious relationship. Your schedules stop lining up. The person you used to talk to every day becomes someone you catch up with once every few months.

Peter experiences a much more dramatic version of that distance, but the feeling underneath it is familiar.

You can't freeze your relationships exactly where they are.

Growing up means learning which relationships you're willing to fight to maintain while also accepting that some will change.

That doesn't make them meaningless.

Sometimes a relationship can matter enormously during one part of your life without lasting forever in exactly the same form.

You Will Lose Things You Wanted to Keep

Growing up also comes with loss.

Sometimes it's losing someone. Sometimes it's heartbreak. Sometimes it's a friendship. Sometimes it's simply losing the future you thought you were going to have.

Peter understands that better than almost anyone.

"This movie is about moving forward in the midst of loss and heartbreak and hardship and trying to figure out how to put one foot in front of the other."

That's an important distinction.

Moving forward doesn't mean pretending something didn't matter. You don't need to erase the past or convince yourself you're completely over something before you're allowed to continue living.

Sometimes growing up means carrying something with you without allowing it to control everything that comes next.

Independence Doesn't Mean Doing Everything Alone

A lot of guys grow up believing independence means handling their problems themselves.

You don't want to bother anyone. You don't want to admit you're struggling. You don't want someone else to think you can't handle something.

Peter has that instinct too.

He tries to carry things himself until he eventually realizes that doing everything alone isn't strength.

"Just because we've lost someone doesn't mean we have to do this alone."

The U.S. Surgeon General's Social Connection resources emphasize that connection plays an important role in individual health and well-being.

That's one of the lessons adulthood eventually teaches you.

You need people.

Not because you're incapable of handling your own life, but because nobody is supposed to handle every difficult part of life alone.

You Don't Have to Become Who You Used to Be

When life changes, there's often an instinct to get back to normal.

You want the old relationship back. The old friend group. The old routine. The version of yourself that existed before something happened.

But growing up isn't always about getting back.

Sometimes it's about becoming someone new.

"Maybe healing isn't about becoming who you were before, but becoming someone new, carrying the lessons instead of the weight, accepting your scars without letting them define you, and still believing that there is a future worth living."

That's one of the biggest ideas in Brand New Day.

Your experiences change you. Your mistakes change you. The people you meet and lose change you.

The goal isn't to make sure nothing ever changes.

It's deciding what you want to carry forward.

Nobody Suddenly Figures Out Adulthood

Maybe the biggest lesson about growing up is that there isn't a finish line.

You don't wake up at 25, 30, or 40 and suddenly understand exactly what you're supposed to be doing.

Peter doesn't have everything figured out either. He makes mistakes. He gets overwhelmed. He doesn't always know what to prioritize or what the right decision is.

He tries something, sees what happens, and adjusts.

That's what most of us are doing too.

Growing up isn't becoming certain about everything.

It's becoming more comfortable moving forward without certainty.

And Here's The Thing

Spider-Man: Brand New Day isn't really showing us how Peter Parker finally becomes an adult.

It's showing us what becoming one actually looks like.

His life changes. His relationships change. He gets rejected. He compares himself to other people. He loses things he wanted to keep. He struggles to balance everything and eventually realizes he needs other people.

None of those things mean Peter is doing adulthood wrong.

They are adulthood.

"Sometimes all you need is a brand new day. And there will always be a brand new day."

Maybe that's the biggest lesson about growing up.

You won't always know what's next. You won't get to keep everything. Some days won't go according to plan.

Then another day comes.

And you keep figuring it out.
