Strengthen your core. Lower back pain in your mid-30s is a removed. Also, take care of your teeth and floss everyday. Start investing early. Any amount you can set aside, no matter how small, will payoff if you start early.

Live below your means.

Wear condoms every time

Also it's okay to not know exactly what you are gonna do with your life. No one else actually does either, as much as they think they might.

Let go of any fear of others expectations for you as soon as you can. Explore what interests you and don’t let others stop you. People come and go, but they’ll come to you faster than they leave if you’re a confident and passionate person. You can only be that if you work on figuring out how you want to live and chase that life.

Travel if you can afford to, it’s an incredible way to learn about the world and meet different kinds of people. Look after your teeth.

Stay away from gambling sites. If you’ve got extra money and want to watch it grow, invest in Exchange Traded Funds (ETFs) with a low/no fee trading account. Stay away from meme stocks as well.

If you do invest, diversify your portfolio. SPY is very exciting but it’s heavily tied up in the AI bubble. Try to more international markets, clean energy, minerals, heavy industry. No matter what happens to the AI companies, we still need energy and resources to build stuff and keep our economy going.

Read about taxable and non taxable trading accounts in your country. Try to use those to avoid having your savings eroded by taxes. You will pay plenty of taxes on your income, so don’t worry about that!

Learn how to clean properly, stains especially.

Practice a few basic but yummy recipes (trial and error for which work for you) and get good at cooking them.

Remember everybody is living their own life at their own pace. Don't feel like you aren't doing it right.

Ask for help when you need it. Nobody can do it all alone.

Stay in contact with friends and cut ties with people that make your life worse.

Don't stop training, don't eat shitty food (at least, not daily), don't believe anything you hear or read and always double check it.

Take care of your body is the only one you have, use sunscreen.

Spend time with your parents and people you love they are not going to be around forever, do things they like.

You have time, don't rush into things. Don't think you are 25 you should have a family by now, life is not a race each person reach goals differently and not all have the same goals. Search what makes you happy and do it.

Worry only for what you control, if you can control it you can fix it, resolve it so look for solutions but don't worry about what is out of your control, you won't be able to fix it you have to accept some things are they are and learn to life with them being that way.

Do the things. Do them. Don't leave them until later. There are always things. If you don't do the now things, thinking you can do them later, there will be other things later.

Not doing the things only puts you behind, possibly forever.

Do the things.

get a dishwasher, always read contracts, be confident during interviews, hydrate your skin, do regular exercise

Vote!

Local, state, Fed.

If you don't vote, you have no rights to complain about how government is functioning.

Do not discard advice from older people because you think "the world has changed" and old people are out of touch.

ALL the advice that the older people in my life gave me in my teens about money/college/jobs/people/relationships was right, but I refused to listen to any of it because they were old and didn't understand my life.

Don't force yourself to learn every life lesson the hard way, like I did.

You'll probably learn everything the hard way...but I tried to tell you.

Start building credit if you’re in the US, but don’t treat your credit card like free money.

Don’t let yourself get addicted to alcohol (or any other drug).

Spend a decade commuting by bike if you can (rain or shine).

Get radicalized by the terrorists (people who just wanna have a nice safe society free of bigotry and hate).

Go to therapy if you struggle with mental health - the sooner, the better. Change gets harder the older you get.

Internalize your rewards for doing something good - don't look for external validation from others that you are doing a good job. This is especially important in relationships. It's great to be appreciated when you do the dishes, but you should be able to motivate yourself to do it and feel pride that you are carrying your own weight.

Who you are now, isn't likely who you'll be in 6 years. You'll change a lot over the next few years as you become an adult. Legally, becoming an adult is the difference of a day. But actually maturing into an adult takes time and effort. Yes effort, you'll meet plenty of adults who cling to their highschool self.

I don't know if alcohol is still placed on a pedestal like it was in my teens, but alcohol isn't that great. It's an expensive poison humans can sorta metabolize. It can taste good, but moderation is key. The point isn't to get drunk. As an adult who can drink anytime I please, is generally would rather just have water.

Now is a great time to get into a fitness routine.

Head to the Winchester and wait for adult life to blow over.

Lots of good advice here and I am not THAT old but here are a few things I wish I had realized sooner in life (in no particular order or theme):

• No one really knows what they are doing, more experienced people usually have just made the mistakes already.
• There is a difference between being correct and getting someone to agree you are correct, the former is the most important and the latter is not always possible or desired and when to argue and when to let someone be wrong is a skill that takes practice.
• The less time spent worrying about what other people think of you the happier you will be and the easier life will feel. In almost all situations you spend more time thinking about whatever it is than the other person does.
• Always strive to be a good and like-able person but always remember that it’s impossible to be liked by everyone, sometimes people just won’t like you and that is okay.
• One friend you can count on is more valuable than 100 acquaintances, guard and nurture your valued friendships like your life depends on it because it might some day.

The biggest thing though, there isn’t one correct way to live your life and anyone telling you differently is probably selling you something. Always try to learn something from every situation and you will be fine, mistakes are a part of life. Anyway, hope at least some of that is helpful!

The fact you had the initiative to ask this shows you're probably pretty intelligent. All I'll add is the perfect life doesn't exist. Do your best to enjoy it and be kind to people.

Don't drink a lot. I've forgotten a lot of good times due to excessive drinking, and it's taken a toll on my mental health. I'm 35 now and trying to make some changes, but I've wasted about 15 years of my life just partying and being hungover. Not to mention the tens of thousands of dollars spent.

On a positive note: find something to volunteer your time doing. Even an hour or two a week is great. It's a great way to meet people, and there is so much good work being done by organizations who always need extra help.

Good luck to you dude, I know you have a bright future ahead of you!

Exercise, have a salad for dinner sometimes, be careful who you date and keep friends you can trust to tell you when you're fucking up.

Meaning can be found in pain and we all face that.

DONT DO IT!!

THERE'S NO TURNING BACK

At that age, I was trying my hardest to figure out what I'm doing, to be together like the older adults.

I'm 39, I don't have a clue what I'm doing and I'm more together than most of my coworkers, many who are older than me.

We're all just trying to figure it out, so when you look up and think you don't know what you're doing, you're with everyone. And if you know someone who says they have everything together and don't have any issues, be wary as they likely have a lot of blind spots to their life.

I just have one. Smart people learn from their mistakes. Wise people learn from the mistakes of others. You won't leave long enough to make all the mistakes yourself.

• Take care of your teeth.
• Wash your butthole every chance you get.

If you're going to go to college, go to a community college for your basics. Same classes, often smaller class sizes, and much less money. Just make sure the credits will transfer first.

18yo old

That's like "ATM Machine"

Open an IRA (or your country's equivalent), invest as much as you and still afford to live. A tiny little discomfort in the beginning isn't the worst thing. That money will grow tax free for year until you retire. The more you get in early, the more compounding works in your favor.

Just be nice. And listen. Always listen and pause before you speak. It will solve sooooo many problems.

Sit down pee when you're visiting a friend's house. Double points if you do the same at your own house.

Live in the present, take time to analyse things. It's ok if you are slower at some things. Every time spent reflecting will enrich your next reflection and bring more peace and comprehension. Be patient. Try new things. Meet people. Hold your own opinions to scrutiny, back them up with evidence. Do the work. Trust the right people. Don't give in to fear or anger. Allow yourself to feel sad. Analyse your frustration and feelings. Talk to yourself if no one is listening. Keep some of your hobbies especially if it's skill dependant going.

Also ffs don't start smoking.

Your brain still isn't fully developed into an adult one. Another half decade or so should equip you with the rest. Take care of it!

Do the things you don't want to do.

You'll do the things you want to do, meaning the things you don't want to do are the important ones.

Don't worry too much about the rat race. Take time to enjoy life and experience things with people you care about. The best moments in life can be really small things.

At the same time, don't waste too much time doing nothing either; use your time well, but use it to develop and improve yourself, learn something useful. Get a job you enjoy or consider important, at least. Doing work that you enjoy or consider important is far more valuable than the money you make. But don't ignore the money either. Just don't sacrifice your soul for it. Don't work yourself to death for a boss who doesn't appreciate you. Don't burn your relationships for money.

Do you know what the genetic difference is between a human alive today and one who lived 100,000 years ago? Almost none.

The real difference is shared knowledge. Every generation stands on the shoulders of those before it. You hold in your hands more understanding than any person in history could have imagined.

You will always be ignorant, not as a flaw, but as a truth of being human. Accepting that is where real learning begins.

Stay curious. Curiosity keeps you open to the world. It grows empathy, invites wonder, and reminds you that every person you meet carries a piece of the story you haven’t heard yet.

And when you share what you’ve learned, don’t speak as though you hold the final word. Speak as someone who has explored, reflected, and arrived at their understanding with care.

Learning is a lifelong conversation, one that connects you to every curious mind that ever lived. So keep asking, keep listening, keep growing. The future needs you.

As someone who wishes someone had told me... Adults don't know what we are doing either. It took me way too long to realize I'm not an imposter pretending to be an adult, we are all just kind of winging it.

As you grow older you'll have seen more stuff and it will be a little easier, but I can attest I don't have a clue what's for dinner, just like I don't know what new headache the next meeting will bring. Live life for life's sake, the clock will keep ticking whether you're ready or not.

Get a vasectomy

Baz Luhrmann - Everybody's Free To Wear Sunscreen

Break stuff and figure things out, take chances and have fun. You've got time. You'll figure it out.

Personally i would suggest not going to university for at least 2 years, work a small job if you have a good living arrangement with family, and save up as much as you can for those 2 years.

Additionally, put some savings into an account that earns interest over time as a way to save for the long-long-term.

Go to the dentist, ask them how to take care of your teeth for the next 80 years, and do it.

If that means cutting down on soda, or acidic espressos, or candy do it.

If that means buying an expensive electric toothbrush with better toothpaste do it.

It's okay to be scared, but do it anyway!

Money is very easy to spend, but Money is so very hard to make. Be cautious with your money

wisdom is often wasted on the elderly. youth is fleeting as are most the mistakes you will make in life at this point.

the following advice is fitting unless you're doing either of these two things:

1. making babies
2. taking a life (especially your own)

Live the three truths

1. you will always make mistakes
2. you will always hurt those you love
3. you will always have regrets.

the older you get the harder it is to recover from these truths. Live your life to your requirements. By the time you're closing in on your 30s, you should start to settle down and find yourself a quiet place to build your life for when you're in your 50s or 60s.

in your 30s seek out happiness and contentment. this will be your foundation to accept your regrets and mistakes. own the mistakes you made along the way, accept them like you would a bruise or blemish on your body. in time they will heal, if only you accept them and move on.

in your 40s harvest your happiness and contentment. accept there are things you cannot do not because you haven't or couldn't but because you shouldn't.

in your 50s store your happiness and contentment with the knowledge that nobody can take it from you, it's yours and yours alone.

60+ feed your soul from your stores, using the memories you made along the way. depending on the life you have led, share in new memories with those around you. celebrate their successes as your successes.

if you're lucky you will build lasting relationships along the way and will have many fond memories. you will inevitability have bad memories as well, but such is life.

personally I lost every single friend I have ever had. I never really recovered from it and now I have no friends. It's one of many regrets, but I never let it spoil my happiness and contentment. I find fulfillment by other means like hobbies, crafting, and family.

I never wanted to be married or have kids, but it feels as if what you think is important today changes by tomorrow. don't fight it, because you'll only be fighting yourself.

life is full of surprises, learn to roll with the punches and adapt to the world. if you don't, life will fucking kill you.

Your social life as an adult is very much what you make it. Go do things that seem interesting even if you feel you'd rather stay home. Chat with people when you're there. A huge component of modern loneliness is that we're able to stay entertained and with a crude social life without seeing others irl, but it's often not actually sufficient. So go get involved in something hobbies, activism, whatever events look interesting at the time. And remember that the things you do now are the memories and stories you'll have when you're old.

You can see a trend in these replies and it's not a good one.

The more discipline you can have without letting small lapses and setbacks get to you the better off you'll be in the future. Don't get set on something (job, relationship, philosophy) until you really know who you are and what you want, and explore WIDELY. Be honest and direct in your communication and you'll have less drama, the trash will take itself out. Find mentors, don't let them run your life. Use your body like a diesel truck.

You spent 18 years learning to navigate a gated world. You will do just as much learning in the next 18 navigating a newly ungated one.

Think about the sort of kindness you would want to treat a younger version of yourself as he fumbled through that learning. Practice treating your new "young" self with that kindness today. It will pay dividends.

Put a lot of thought into your college major. Pick the hardest one you can actually do. Take it easy on the substances, especially stimulants and depressants (yes, this 100% includes alcohol). Exercise regularly, sports are ideal because they're also social so you're getting two birds stoned at once. If you don't like flossing, buy a water flosser. Don't have kids until you're in a stable relationship and you both have good jobs. Get used to living on 90% of your salary, the difference in terms of stress between slightly under-spending and slightly over-spending is enormous.

Don't send dickpics. You never know when they'll show up on a leak.

Im probably not wise enough to give advice, but in general I think it's while you are young that taking big risks is more worth the trade offs.

Im talking risks like career wise or investment wise, business wise, etc.

Know thyself.

What irritates you the most in others are probably unconscious parts of yourself you supressed.

If you are male, you can get male pattern baldness in this age, but you can stop baldness by taking finasteride.

Stick to your principles & rule of law like flies on shit

Believe in yourself, especially if no one else does

If it's wet and ain't yours, really think about it before you touch it.

Bring a towel.

Be a goldfish.

There's probably only one play on this quarter. Don't look back and think "what if..."

Specific advice like "save your money" and "enjoy your money while youre young" and "focus on education" and "forget education get a job fast" are all too nuanced and will likely get ignored anyway.

This "song" pretty much covers the important stuff.
