I think it's an expensive hobby for anyone, both in college and once you graduate with a professional career. That's why many seek to fly professionally (still taking a financial hit non the less). Your best bet for now is to save up for your "Private Pilot's License" and once you get your PPL, fly whenever money allows, and eventually get the instrument license and multi engine rating...

Thereafter, once you graduate and start to work in whatever profession you choose. You'll be able to buy into a flying club, buy a plane, or at the very least pay the rental fees.
