This COULD be one of those life changing decisions, so take your time deciding. If it had been me, and was offered a job at 40k/yr, or, continue my flight training, make pennies as a flight instructor, then make pennies as a regional FO, with the hope of making 60k+ after an upgrade....well, I would have stuck it out, got my ratings, and followed my dream. Luckily for me, i didn't get an opportunity like that, so i continued my training anyway.
After getting in though, doing some time, i got out, and found a normal job, decent salary, good bennies, and hung the hat up, might get back in eventually, but A LOT will have to change before i do, best of luck w/ ur choice.
