I changed majors my senior year of college; actually graduated with more credits in my first major than in the one I got my degree in; I went back to school and 35 years later got another degree in my first major :-) My advice is to follow your heart/interests, wherever they lead. You cannot "plan" for the future, what you will be interested in then, what you will be able to get a job doing, who or where you will be, etc.

If you think it would be a good idea to get a "practical" degree you think you could get a job with, then figure out what you would like to study (computers? nursing? HVAC repair?) and give it a try, see if you like that. It is never too late to change, never too late to start over; it's your life, you can do whatever you want! There's no script.
