Some pitfalls you might experience along your journey are...
The military doesn't fly very much, and they always want some type of commitment. Usually a few years.
The worldwide pilot shortage is a gimmick that i've heard for the past ten years. Too many variables come into play such as world economies as a MAJOR ONE. Don't plan on it happening. And don't base your decision on becoming a pilot on it.
The airlines are always looking ffor qualified people, and you need to be one of them at their doorstep at the right time. The airlines might only need a few pilot in ten years. But if the timing(very important uncontrollable variable) Then you'll be there to meet the demand.
My suggestion is to go to flight school first, before college, and get all your liscences, and instruct while in college. You will probably get college credit for your liscences anyway. It would take about 8 months at a 141 school like FLightSafety
. A great program despite JFK jr. killing himself.
My experience was that college was no place to do flight training.
Their will need to be some way of gaining experience between finishing your college and a commuter. The commuters will not comer banging on your door. This is when you will understand the meaning of "will fly for food". You need experience.
