Definitely don’t have to choose a major now, but I understand wanting to. DD’19 was always thinking about it then.
If you do want to poke around at some ideas, go to some colleges’ websites and read through the list of majors. When one sounds interesting, go to their catalog and read the course descriptions for that major. See if it still seems interesting then. It helped DD. Then she went to a college that had every major she had considered, though she was pretty set on hers by the time she arrived. It was one she hadn’t even considered until I was reading random majors off a postcard her future school had sent.
