Airline Pilot

People usually quit pursuing the job of being an airline pilot early on in their training phase, and it's usually the money that causes them to do that. If you go the military route, the military pays for your training, but if you go the civilian route to a flight school, then you're going to be responsible for your training either through student loans or out of pocket. It can be upwards of $100,000, and when people realize how much it's going to be, that's usually a very daunting number, and they will quit their training before it's even finished and go do something else.
