Brutally, it boils down to: have you got the flying bug or not? If not, find something else. Banking is good.
Would I do it again? Like a shot. I've loved it. I've seen the world, flown all types from a turboprop to a 747-400, retired, and doing it again, until they call security to carry me off the aeroplane feet first kicking and screaming. But don't expect to find it a goldmine. And the responsibilities you carry could keep you awake at night if you let them.
