average person changes careers 4 times in their lives (although it could be more these days)....
just get good grades, find an area that you are interested in, maybe some generic like computers/IT and as you go through it you might want to specialise....you might swap degrees as 50% of people change degrees....I changed my major in my undergrad degree only to go back to my original major in my Masters due to employment
oh yeah, if you can, when you're studying, work at same time as education is overrated, experience counts....unless of course you are in a highly technical field, but in most cases, experience counts....as long as you're flexible and a good learner, you'll be fine....
that being said, I think it's time for me to make a career change
