Hey mate, don't worry about all that crap about following your passion. At least not yet. I assume you are only in your early twenties, yeah? The majority of people in this world have no idea what they want to do, (work wise) with their lives at your age. You might be slogging away at some course not really enjoying it, but just doing it to keep busy and stay off the streets, and you will be hit by an epiphany, and you know what; it just might be that what you really want to do is stick your hand up a cow's behind!
Hang in there, it will all fall into place.
Why don't you do your IT course by correspondence, or is that not possible?
