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.

Treat others the way you want to be treated.

If you don’t know, ask or find out. Knowledge is rarely a Bad Thing.

Take care of your health. It gets a lot harder as you get older.

Seriously, go to a library. Pick something. If you don’t like it, return it for something else. If you do, get some more like that one. But don’t be afraid to branch out.

Edit to add: pretty much everything said here is really good advice.

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!

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.

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.

DONT DO IT!!

THERE'S NO TURNING BACK

The lattory is a 'Stupid Person Tax.' Meaning that stupid people throw their money at it because they buy into the feeling versus the logic behind it. "The overall odds of winning a prize are 1 in 24.9. The odds of winning the jackpot are 1 in 292.2 million." source

You had better odds of you, a sperm cell, fertilizing your mother's egg, than you do currently of winning the Powerball jackpot.

How much sperm is in semen? A typical sperm count may range from 15 million to more than 200 million per milliliter of semen

Let that info sink in for a moment.

Don't try and "make it" by 22 and realize that those who appear to do so are faking it.

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.

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.

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

Take care of your teeth. Many loves will come and go in your 20s and maybe even 30s, but if its a life partner you want try focusing on yourself and they'll appear out of thin air. Friends are important but not as important as inner peace. If a job offer 401k start investing as much as possible as soon as possible. Everyone is going through their own crazy messed up life so be kind. Puff, puff pass and enjoy your 20s as much as possible while not losing sight of your goals. Goals are EVERYTHING, set the achieve them and set them again. Heartbreak and death are integral parts of being human. It's important to sit with and process the pain as long as YOU see fit. Death will come for someone you love someday, don't let drugs or alcohol be your medicine

• 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.

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.

Lift wieghts and or do some other physical activity. Its good to have two hobbies; a mental one and a physical one. The muscle you build now will be with you for the rest of your life, and its mucb easier to do it now than when you are middle aged like me.

Dont focus too hard on girls, just live your life and enjoy the experiences and relationships you build with all people; everything else will follow.

Travel, with a focus on the physically taxing things that are harder to do when you are older.

Invest what money you can, compound interest is real and it is the path to wealth (eventually).

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

Before you get a career, live and work in another country or travel on a budget for a year. See other places, meet new people, learn lots of new things and get out of your comfort zone. Some people just walk or bike across a continent with a tent.

You won't be able to do it later in life when you have a job, family and commitments.

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.

That's like "ATM Machine"

Here's my rantomendation:

Don't hit, mame or kill anybody ever. That includes when driving.

When driving pay attention to the road and only to the road. Ignore work or home or school problems. Don't zone out.

Listen to your parents but don't listen to the parts that limit you. Be gay if you are or straight or smart or whatever, be you. But listen to the good advice.

Fuck a lot

Eat healthy

Pay attention in school and learn from others. Be observant and follow in other people's steps long enough to learn to blaze your own path.

Don't get a school loan or max out your credit cards.

Work thru school in a light non interrupting way. Don't get an 8hr job, just something part time.

Get that diploma and go find a job where they pay you for what you know. Work on something you like to do. Work to live, not live to work. But to get here, don't skip steps...sweep the floor before you shoot for CEO.

Mourn your losses, everyone dies. Be happy with yours while you can. Family is everything and there's not much more than your own personal desires beyond family. But if you don't have kids by chance or by choice, still be happy. There's plenty of people who choose not to have kids or be married or be in a relationship. Have bobbies. There's a lot of you time towards the end part of your life. So Hobbies are good. Watching people is a hobby.

Be at peace. Don't hate and help others not hate. Racism is the worse. So if you can help a racist person to accept others then that's good.

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.

If you aren't already, start going to the gym now and don't ever stop, or you will regret it by your late 30s. I stopped going at age 30; it's only been seven years since but I can already feel my body falling apart. Everything hurts all the time and it doesn't stop hurting.

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!

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.

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.

Baz Luhrmann - Everybody's Free To Wear Sunscreen

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.
