From my brief experience with University (just went into 3rd year, after a year of coop), it's mostly to meet people and expand your circle of friends. In the real world, you'll use like 20% of what you learn, maybe even less.
So just take something that you enjoy, don't sweat it too much, and expand your business.
I regret taking a specialist (double major in one program) of computer science... I'd rather be doing half and half comp-sci and something else, like commerce, management, german, history or something.
