Hey BB, How old are you?
If you are talking about become a pilot, First good thing to taste aviation is to go in aviation airfield and register to a club, talk to some instructors, students, and others passionate/wannabe and do some hours on light aircraft.
Especially if you live in the USA, it is far less expensive than in Europe
As said Stuart, there are many differents jobs under the word Aviation, so you have to think about it, what will you like,to Fly aircraft,to build them,to fix them etc...
As for Pilot, it's indeed quite expensive, you have to be sure to well understand what is really a pilot job, because it's a huge investement and if you find out the job is not fit for you after 80000 dollars spent, well it hurts
That's why having some contact in aviation club, or others, is quite important.
You have also military way, where everything is paid by army, you are engaged for 10 years maybe. So first military aviation and then back into the civilian stuff.
If you have question, don't hesitate.
