High school really doesn’t expose you to many, if at all, real careers. I essentially lucked into the career that I’m in. I wouldn’t be that concerned that you don’t really have any ideas for a career that you’d be interested in - that’s pretty expected.

That being said, you probably should find some interests. Do some volunteering if you’ve got no idea what to do. There’s a lot of good community work that needs to be done, and it’ll expose you to many real careers
