I only recently started flying commercially, after a long time 'getting there'.
The flying is generally great. The guys I fly with have become friends. And I am generally happy.
There are days when things really p**s me off, but there are more good days than bad, and thats important.
I changed career. The previous career had me working upto 3 times the monthly hours. Trips away were so budget constrained that the hotels were really awful and virtually no allowances. I had been made redundant 3 times. on average, once every 5 years. Companies going broke through bad management. And slowly having your freedom removed by new technology or working practices.
I can only conclude that aviation is like most other industries. (at least in the UK). I do admit, I did expect aviation to be better. But I won't be going back to my old job.
If you are here to fly and enjoy it, keep going.
If you find you are having more bad days than good, for your own sanity, do what you can to find something else.
