Keep learning new things.
Learn cursive and develop your own handwriting.
Writing down things physically makes learning way easier. And keeps your brain young - because, there is a reason why dementia is hitting some people in their 40s.

Edit: brush your teeth and floss every day. If you don't like to floss every day get a water flosser for those days.

Be willing to burn bridges. Some people really do need to be told to fuck off.

Never, ever stop asking why

Wear Sunscreen

If I could offer you only one tip for the future, Sunscreen would be it

It's way easier getting in shape young. Don't put it off.

Start saving for old age now. It might seem like a long way off, and you might not have much money right now to begin with, but being young and poor is way better than being old and poor.

but as much effort as you can into math. There is the common trope about it being useless and that is I think due to peoples misunderstanding of it. Math is mental abstraction. Math problems are like excersise. No on complains push ups have not real world value. Its understood that doing them gets your body in better shape to do physical things. Similarly math helps your mind be in better shape to do mental things. Unfortunately you don't really do it after you are no longer in school so its not bad to try and use it whenever you can. Add your purchases up in your head and try and figure out price per quantity and compare products. do suduko. Also grab elementary logic if you can as it gives a math like framework for reason.

Wear sunscreen

Stretch, hydrate, learn. Continuously.

don't listen to your elders, they're the dipshits that have the planet in this mess politically and particularly ecologically, they don't know shit.

Don't make trends your identity.

You don't want to look back on your life and all the photos you have of yourself, just to realize every fashion choice, purchase, event you went to, and way you talked was all because it was seen as cool, trendy, or "normal."

Live your life in a way that feels right and true to who you are, and what your values are, not what anybody else things is "right" for you to do.

Educate yourself, and question everything. No one is worth following blindly. If you don't understand the "why" of something, keep digging until you do. Critically thinking is the most valuable skill you can have, so develop it as much as you can.

KILL YOUR MASTERS

If you fear dying you're already dead. Always for love, never from fear. A better world is possible. Coconut oil is a 1:1 butter substitute that's both cheaper and better for you

• People are the most suspicious of the behavior they are most guilty of. The guy who thinks everyone is stealing from him, is probably stealing from everybody else. If it's your boss, keep an eye on your paycheck. The person who always thinks their person is cheating on them, is probably a cheater. People do this because they're trying to excuse they're own behavior - "I only do it because everyone else is doing it to me," even if they aren't.

• Commit to doing something difficult, even if it's just a hobby, like running, working out, playing a musical instrument, writing, painting, learning a language, cooking, reading classic novels, birdwatching, etc. Having something that's important to you, and investing deeply into it, will fulfill your soul, and give you something good to hang onto when times get tough. And they will get tough. And don't tolerate people around you who dismiss or are disrespectful about it. It's important to YOU, that's all that matters. Their validation is irrelevant.

This life has no meaning. Absolutely none. Do what you enjoy. You don't need a "purpose," grind culture is toxic and will only lead to burnout. Slow down and listen to the birds sing.

Learn a second language and keep up with the language your parents speak. You will regret being a brat about not wanting to speak this language especially as your family members pass.

Languages are the one thing that gets harder as you get older. Kinda why immersion schooling seems like a decent idea, even if it delays other skills a bit.

Do your best. Make the best choice you can and consciously decide against second-guessing yourself later. Feel free to learn about yourself from any inclination to second-guess, it could be your morals chaffing against your actions.

Be kind. To those you love and those you don’t. Give yourself some grace when imperfections monopolize your focus.

Learn about yourself. It’s going to be a lot easier to make decisions when you know yourself.

Dont do any drugs harder then psychedelics. But especially dont do opiates and benzos. I would rate opiates, besides, and alcohol as the worst drugs to use.

Yes I am an alcoholic, but I avoided the other two. Honestly wish i had access to clean cocaine because id probably prefer that over drinking. Saving opiates for my elder years because im sure I will be hurting alot by then and will need them.

However, its your body. You choose. Heck the rules. Isn't it obvious the rules never mattered? Some think it is a recent phenomenon, but we are only being publicly informed. it has always been true. Oh the slaves are free? Guess they are prisoners now (slaves).

Learn how to micro dose acid, lift weights and eat right, don't sell your soul to some corporation

There's usually more than 1 way to do something.

Sometimes people get caught up on wanting to do it the best way, and then they just dont do it at all.

If there's an easier, less ideal, maybe slightly more wasteful way to do something, and its the difference between doing it or not, just do it that way and dont get hung up on perfection if the alternative is not getting it done.

If its something that needs to be built into a habit, it might be enough to get you started, and then maybe you can move on to the better way in the future.

Edit: just to clarify, often times the outcome is the same but people get caught up on the how vs just getting it done. Don't get caught up on the best how if there's another way that'll also work that you will find easier to do.

My advice would be not to listen to advice people on the internet give you.

Does anyone have advice specific to adhd or neurodivergence in general? Things you found helped you that took time to realise?

Don't let your curiosity fade

Maintain open minded compassion for those different from you

Never be fully convinced you understand the best way to do anything

In disputes between the affected and the unaffected give added weight to the most affected

Learn to recognize a moral panic, and even if you have concerns related to it don't join in. It's the group dynamic equivalent of spiraling and catastrophizing.

Don't drink your calories unless you want to gain weight

Don't buy your wife a wide vase. Just get her a normal sized one. Otherwise you'll have to buy twice as many flowers for the rest of your marriage.

Don't get a job

I don't know about number four my friend. I was going through some of my old CD cases of that long ago and there's more than a few that I deeply regret.

My advice:

1. Don't trust the advice of generations that have left a world worse that they were born into.

2. 

Don't get too attached to anything.
