Just like everyone else here says - diversify. If you read the regional boards, you'll see the outlook for the time being is kind of bleak. It will get better, and you've got plenty of time to watch and time your leap into aviation.
When I was in your shoes, I dragged my mother to an Embry-Riddle presentation at some upscale hotel in Atlanta. I was spellbound at the idea of a school where so many great pilots had been produced; mom was shocked and awed by the prices.
The parents kept me on a short leash and I went to a local 4-year school.
Here's my suggestion. Pursue a basic 4-year degree that's worth something: Accounting, business, education, something like that. Find something you can bear the idea of doing if you need some money for a year or two from time to time. Do your flying lessons at the local airport and knock out your ratings as quick as possible. If you can have your multiengine instructor before you graduate, you're all set.
You've got a lot of good advice posted in reply to your question here. Choose the path you desire, and stick with it. My track had me wandering the country all summer, every summer, and it took a little extra time to get everything done. (finally got multi-commercial at 27, hired by the airline shortly after that.) But.. I worked my way through and walked into an airline career dragging about $15k of debt... not the perfect setup, but better than most of my classmates. That's my biggest bit of advice: minimize your debt in training loans so you don't walk into your first year of airline flying with a monthly loan bill bigger than your paycheck.
Don't laugh. It happens.
And don't scoff at the idea of instructing. I did. I don't now.
Like the others said.. pop in a few short posts to get up to 10, and feel free to IM me if you have any questions. I'm not the greatest idea man here, but I can tell you some mistakes I made and how not to do them
PS: When I go home, I give my momma a big ole' kiss for not letting me go to Riddle. ;-)
