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.

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.

pick up the "analogue bag" trend. none of us older than you approve of the internet today: we had a different place to grow up in online. you will be the happiest and most hopeful person around- others will remember your calm and seek you for comfort.

stop using AI. period. your brain is developing, let it suffer the growing pains of wondering what to draw; of which source of knowledge learn from; how to compose your thoughts. you will be the most intelligent person around- ever increasingly so as years go by.

age old traps checklist: status, whoevers the most popular that moment, flips on the head as you grow up... everyone will Hate how the most popular person behaves now in a few years. be humble if you're the popular one. at the sane time enjoy yourself: if you wanna indulge, indulge. saying stupid things from your heart is indulging. listening more than you speak is humble. that's the secret to popularity that lasts beyond school years.

hug all around you. say hi to everyone around you, even those you don't feel are cool- that you'd get bullied for associating with. that's all we adults are doing: catching up on hugs and greetings, because it helps our mood and makes us feel meaningful wherever we have to be.

learn an instrument, or an art, or a craft, or a sport.

say no to drugs. period. your brain and body are fully developed when you are 26. then you don't get as addicted and have an easer time finding a balance between partying and cozying up intimately in a couch. statistically you'll end up regretful if not abusing drugs or being abused while doing drugs below 26 years old. i can attest. drugs don't fix problems. they hide and let problems infect other parts of your life.

say no to sex that makes you feel pressured. as a guy i got status from chasing sex at your age, but if fucked me up to only be liked for being attractive. friends who cuddle are more important than acquaintances who fuck. one validates you as a human being and makes you feel seen. the other hollows you out while forcing you to become a person for the sake of others to feel seen.

be outdoors. pet animals. eat vegetables. drink water, not soda. drop food additives like "flavour enhancers" (e621) and aromas (vanilla aroma is made of literal cowdung and fossil fuels.) companies are not your friends: you're as cattle to the companies, so yeet their brands. wear natural fibres and what you like.

welp i have more but idk if you'd read all

If you don't know yet learn a second language. Chinese seems the most useful nowadays.

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.

Some of the other comments touch on it, but usually mixed with other items, so let me reiterate. Your metabolism is going to slowly wane. Keep an eye on your weight and reduce your calorie intake now. It’s really easy to think “meh, so I’m 10 extra pounds, I can easily lose that later” but by later you will be 15 extra pounds. If you’re gaining muscle, that’s one thing, but keep yourself from gaining fat as much as you can.

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.

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..."

When I was in high school, I wanted to go to a couple specific unis. Being rejected was one of the best paths ever. I went to community college, made lots of friends, had amazing professors, took part in lots of programs where I made long term friends who even stuck with me to transferring to my current uni. I took a bunch of fun classes there that allowed me to get the skills I need to land the internship I have.

So my advice is, as a you guy, you have lots of time so test the waters, experience stuff, have fun, and you'll enjoy whatever it is you end up in.

Don't be that one guy who has to finish college in 4 years and then figure out that school didn't teach you anything and you can't find a job. You never took fun classes, joined programs, join clubs.

Believe in yourself, especially if no one else does

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

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

Know thyself.

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

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

Being responsible is always beneficial. Sometimes you don't get/feel those benefits, but everyone is grateful when their bus arrives on time :) Just don't forget to being responsible with yourself too.
