I did 4000hrs in GA, the hardest, most financially destructive time but I learned a lot and had some fun. 25 years in 4 heavy types since and I still love the job but hate the lack of sleep (Longhaul). If you want it, do it. Just go in with your eyes open and be thankful that you have a backup career. My first question to young people looking at a flying career is “do you like to eat rice? Because that is all you will be able to afford”. If you go into an aviation career, it’s because you like flying, any other reason will leave you disappointed.
