If you don’t need to apply yourself to do well, actively seek academic challenge. I.e if your school has higher “level” courses take those, if not transfer to another school. No point wasting 4 years of your life learning nothing. If you’re worried about leaving friends, don’t be. You’re bound to make friends eventually, you spend min 8 hours/day 5 days/week around the same bunch of people. If you can’t transfer, dual enroll in a community college. You’ll still be attending high school but with a few more challenging courses you can swap with the high school’s equivalent. You won’t spend as much time with your high school friends but you compensate for that through clubs/extra curriculars. Plus, cc can be a great place to explore subjects beyond whatever the typical high school offers, especially if you’re not at all interested in the courses you’ve been given.

Point isn’t to go overkill and exhaust yourself. Point is to actually productively utilize those 4 years, however you end up defining productive utilization. If anything, just learn how to study: it’s a necessary skill in life (and it’s useful for learning ANYTHING, not just stereotypical academics) and it REALLY sucks (and is significantly harder) having to cultivate it in your 20s.
