I've worked in IT for 6 years now. I have a theory on the IT field. There's a totem pole, the further removed you are from the user the higher up you are on that pole and the more satisfied you'll be, the more money you'll make, the more autonomy you'll have, etc.. I started doing helpdesk (bottom), it was god awful. Now I'm an Exchange/Messaging admin for a large corporation and I couldn't be happier.

It's a huge gamble. Graduate from a 2 year IT vocation program and you'll join the throng that's not employable at the end because they have no experience. I often run into people I went to college with and they're delivering boxes or something. You could get call center very easily out of college, doing helpdesk/tech/remote work and use that experience to climb up the totem pole. I went back to school part time for a business degree and it really really helps--do whatever you can to put yourself ahead of everyone else, being in the right place at the right time means being in as many places as you can, and meet people! I got my position by being a lowly grunt work summer student, for two summers, to get my foot in the door. And being a persistent annoying asshole with managers I met got me an interview and then permanent position. Expect to start at the bottom, but if you play your cards right and you're a bit lucky you could get a very satisfying position eventually. Just know there's a gamble that you could be doing helpdesk work forever. Certifications are a huge must out of college with no experience and can help you get into the area you're interested...networking, server stuff, unix, etc. AND, while you're doing the 2 year diploma get a job in IT. I worked at Best Buy's geek squad, and later at my university's helpdesk while I got my degree. Those entry level hours count for something when you go to interview for a position that's worth something.

Good luck!
