Sounds like you were fed bad info, and bit on it. For that I say I'm sorry. I was given plenty of brochures when I was just starting out, and they all had pictures of gold epaulettes, big shiny jets, pilots with big smiles on their face, and the promise of money and a good time, but I didn't bite on those fake promises. I don't know what your situation is, but I know I made sure to prepare myself for the worst, while hoping and striving for the best. So far I've enjoyed my ride, but I've only been doing this for less than a decade professionally.
I had plenty of older, and some would say wiser, pilots tell me to quit because it's not worth it. Well, I can say one thing; I would never tell an aspiring pilot to give up and find something else to do. I know my dream as a kid was to be a pilot, and if flying is their dream, and they were anything like me, nothing is going to sway them to another career. Instead of telling them how sucky it is, I'm going to try and motivate them. Not with shiny brochures and fake promises, but with a little bit of reality.
It's a hard road, but hopefully on the day I retire I'll be able to look back and say it was worth it. If not, I'm sure it'll be an interesting ride either way.
