Get an engineering degree
Aviation is a very volatile industry, and you should be prepared for anything. Remember, Don't put all your eggs in one basket. If you are really serious about aviation, get a degree that will help you in aviation, but will also be a backup incase your aviation career turns sour.
Engineering is a great example. I just finished my degree in aerospace engineering. I know all about how airplanes and their respective systems work. This gives me a leg up for flying, and a great option should my flying career take a turn for the worst.
