You hit the nail on the head. Aviation can be a huge disapointment, stop and think about your options before it consumes you. Gulfstream-IV driving all over the planet for low wages, long duty days and weeks on end away from home and family is really depressing. Probably not what you were looking for but equally as important to understand before sacrificing it all and regreting it. People are turning and running from the industry, failing companies, low pay, layoffs, poor quality of life, dysfunctional flight departments, and the pressure to fly unsafe airplanes. At the end of the day, do you see yourself pulling into a crap hotel late in the night and not having eaten for 10 hours, having to deal with maintenance about a broken airplane during your rest period, having enough time to grab a few hours of sleep and then climb back into your seat with unhappy crew members, thankless passengers and do it again. Now, lets see, logging of flight time in order to get one of these crappy jobs? Don't bother! Go to Dental school or something else, make great money, have a life and hire some lame like me to fly you to any destination of your choice, and I will even thank you and beg for your business again. That is corporate aviation in its simple raw form. Best wishes.
