Well guess what? You don’t have to decide now. Many schools number one undergrad major for freshman is… Undecided… Do that. It will give you time to discover yourself. Many of your friends will NOT end up in the careers they thought they would in high school as a junior. Many college students change their majors… Twice!
Do things and take classes that interest you. Take classes with lots of rigor (if your able to). Get the best grades you can. It’s silly for anyone telling you what to do for your livelihood at this point. But definitely start to look at your options.
BTW - many people make less then your goal amount and still travel a lot and have kids before 30…
