I did my licence a few years ago as a late starter after a good well paid career in another industry.
I was fortunate to get an airline job from the start and to be honest I hated it from about the second week. I am used to working in a polite, fair environment and the culture within the airline I was in was schoolboyish. Told what to do, when, where and how. Roster was mad, always a mess, and changes ALL the time when you have things going on in your life, hotels at the cheap end of the market. It was exciting first time flying the aircraft but once you have done it, its quite boring and the SIMs are always repeating the same thing, again and again but slightly different. Its a very repetitive job in a very sterile environment and I found it quite boring and something I got over pretty quick. Playing football with friends is much more fun and exciting.
I spent alot of time and money to do it which on one side was a complete waste but I wanted to do it and I did, so it was a success on the other side.
Am back in the other industry and I am much happier appreciating what I had even more.
Oh yes the money is very low for what you do. I think the younger you are the more you can put up with the BS, stress etc and the business case for the investment is more worthwhile as you can earn good £ quicker before family commitments come along and quality of life is more important.
