Don't too much about grades or college admissions. It's really not worth it, especially with how it's pushed as the only important thing. Make sure you pass all your classes but don't worry about getting all A's or getting into the ivy leagues

Don't take out student loans. Ever. It's a scam

Community college rocks. Don't be afraid to.go, but it's not a silver bullet

Read books. Especially the ones that they're banning and pulling from libraries. Get a good eBook reader for your phone, use Anna's archive.

Self education is more useful than school, make sure to do a lot of it. Teach yourself stuff, learn skills

Learn how to tell which adults are full of crap and which ones are worth listening to

Don't let the fascists take away your rights, including whatever "protect the children" moral panic is going on, that's just a scam to control you

Speaking of scams to control you, question the religion you were raised in

Learn the signs of abusive relationships, it's super important and no one ever emphasizes it. Don't tolerate abusive treatment from anyone

Don't gamble

High school is like prison, the social scene is totally artificial. The only people you'll even talk to afterwards are the friends you made, and even then only if the friendship was deeper than "we had the same class together"

Internet friends are just as good as IRL friends, especially if you are having trouble making IRL friends because your school/neighborhood sucks.

Traditional life paths don't work anymore, our time is one of radical transformation. Feel free to experiment and see what works for you
