You are still evolving as a person. You do not need to know your future job or even college major yet. Continue to explore various subjects and eventually you will find those that appeal more than others. I recall stating I was only going to take the minimum required scienc in HS- I went on to major in chemistry and while in college decided on becoming a physician. Physicians have many varied interests that have nothing to do with medicine, btw.
Do not worry about your ultimate post college job. Do not worry about a future college major. Continue, as above, to learn. Eventually- years from now- you will figure out a path. And- even after you have a career you may find you are making changes. Life is not a straight line with everything mapped out. Allow yourself to enjoy the present and the future will work itself out when the time comes.
