DO3R17-
I can see by your writing that you have the passion and fire in your stomach. That's awesome! This alone will get you very far in the airline pilot profession.
First things first. No matter where you decide to do your flight training, hour building, and 4 year degree studies, being a pilot means you're in a business where the contacts you make create the jobs you desire. Simply put, that means that you will advance further and faster when you reach out to people you come in contact with. Nice, friendly people go far in this business. I honestly don't care how good of a pilot you are; the FAA wouldn't license you if you were dangerous. So create some differentiation in yourself by being likeable, professional, and interested in people around you as you build time and finish out college.
I went to a small college in Dallas while flight instructing part-time. The contacts I made between 250 and 1500 hours total time were the contacts that created every job I ever got, up to dream job with a major. Build friendships and contacts along the way, and you'll do well in aviation-- I promise.
It doesn't matter what your degree is in, although like the prior post said it's good to get something non-aviation so your eggs aren't all in one basket. Wherever you go, make sure there's lots of activity. Where there's lots of CFIs and business jets, there are lots of jobs and networking opportunities. DO NOT go to a small mom-and-pop school sitting by itself on a 4,000 foot strip in Bonham, Texas!
All the best to you as you finish out high school and begin your upwards trajectory. Drop in once in a while and let us know how you're doing.
