I went a similar route to ERJ135. I began flying lessons at a young age and I think it served me well. I also read everything I could get my hands on, from "Flying" magazine to technical manuals to Ernie Gann. Don't neglect aviation and airline history. A good university aviation program is fine, but in my opinion they are overpriced. A four year degree is still essential if you want to position yourself for an airline career, but it definitely does not have to be in aviation. A degree in anything that interests you will expand your worldview and can open up some other doors if a piloting career doesn't come to pass. It's usually cheaper to get a non-flying degree and get your licenses/ratings on the side--shop around and compare. Don't overlook the military option, either. I wanted to go that route but was unable due to less than 20/20 vision. So talk to someone who has been there and done that (not just the recruiter). Good luck!
