I still don't know what i wanna be in life

You're trying to define who you are based off what you want to do to make money. Success isn't a real thing. Don't let society choose anything for you, you can always hitchhike travel and try writing music or art. Society is crap anyway.

You better get a sense of urgency because you're working in fast food service for life otherwise. Do some part-time jobs, work in the summer. Figure out what you excel in and enjoy.

It's obvious that you aren't finding your purpose in school. You need to build some experiences.

I'm the same! I do not know what I wanna do, but I guess I will see. No need to stress about it now

Do what you are interested in and makes you happy then do it. If you feel like being a sanitary technician (fancy phrase for garbage man) then go for it!

Did read one thing that makes sense. Go take a 2 year course in SOMETHING that vaugly interests you. By that time you may have a better idea.

You could also talk to a councilor and/or take an aptitude test.

Are you boy or girl?

Firstly, forget all the pressure about it being such an important choice, life consequences etc. The trick is to choose *something*. You can always change careers later in life, like many people do.
So, think about what you enjoy, what you're good at and all that stuff, obviously. Make the best decision you can. Of course. But make a decision. That's the more important part.

Cos, what you don't want, is to be paralysed by uncertainty or fear and to put it off. Hopefully that's not a problem for you, but I just mention it because that's way worse than going down a career path you regret later (experience). Career can always be changed.
But yeah, totally, completely normal to be uncertain about it. It's hard when you're a person with lots of interests and general aptitude for lots of things.

I would recommend only getting a 2 year degree for now. If you don't know what you want to do, it's likely your major will be a waste of money. Do internships, read books, and anything else that can help you learn what you love the most.

Valenteer as much as you can. Do free internships. That way you do the actual work in that field and you can decide if that's something you want to continue doing. I got out of the military at 27years old and I still didn't know what I wanted to do. I always been intrigued about computers so I went to college for a degree in computer Information Systems but when I did an internship it bored me. I now have a baschelors in Computer Information Systems but I got a job as a Financial Analyst for the Federal Governmanet and I enjoy it.
