I want to take anthropology, but I don't want to regret it

What can I do in highschool to test out anthropology as a major? I'm looking to major in anthro, and then maybe go on to be a professor or a teacher (because I love teaching) but alot of people are telling me that I should "do my research first" (lest I end up a barista according to some). I've been scrolling this sub for a while now, but I think going out and actually involving myself in the study would be better.

Any ideas?
