One tip I would pass along for you is that don't get into IT if you think you'll be the hero. While we generally are the heros in any given business, as we keep all the stuff they rely on for doing their job going, we are almost never treated accordingly. IT is the field you get into because you love technology and you like doing a job right. You also like that there is no ceiling on what you can learn, and that the field is so diversified, you can go practically anywhere and everywhere. But you're not the hero. People treat you fair at best, most of the time. People will blame you for every problem imaginable under the sun. You will beg bosses and managers for new equipment because it's not a need, it's a desperation, and still get denied. Then, something will break and you'll be blamed. You will get woken up at 2AM by an alert and you have to go into work because everyone else who goes in at normal times relies on you having that issue resolved in 5 hours for when they get there.
You'll learn a lot, and IT is even more about understanding business needs than most people realize. If you want in on the game, then welcome aboard!
