I hate to sound like a broken record, but I concur with the comments above. I've been in the military for eight years doing computer repair, telephones and networks. I'm A+ and CCNA certified and I have never completed a college degree, though I am working on one. I have to say pound for pound the best thing to study is what you love. That is what you are going to be most successful in, precisely because your passion for it will drive you to excel. You will be hating life in a few years if you chose the thing that everyone else did, or you thought would pay the most, or what you thought would land you more jobs. There are no sure paths to success, however pursuing a career in something you are passionate about is the surest.
Find what it is that interests you most and pursue it with every fiber of your being. Speaking from a personal standpoint, it hasn't all been frolicking through fields of wildflowers. But when push came to shove my curiosity and interest in the field of work I had chosen was what made me stand out. People can tell when your heart is in your work. It will be entirely self-evident by the boldness with which you to take on unfamiliar ideas and new projects, and the tenacity you show in solving difficult problems.
Keep this in mind also, on the whole the information systems tech will deal directly with customers more regularly than a programmer might.
1. Find your passion
2. Be the best you know at it and never stop learning more
