I started after I was 30, went north, worked hard, moved around and now in a capital city flying a turboprop twin (5 years later).
Am I earning anywhere near what I was earning in my previous career? Hell no!
Did I have to work my arse off? Yep!
Did I live in the middle of bum F%ck nowhere earning a pittance? You better believe it!
Did I have to learn to just smile and nod and keep my mouth shut when when you encounter some very "special" operators? <sigh> Yep...!
Did I make life long friends and have an adventure of a lifetime? Bloody oath I did!
If I had a glass ball and had've known how hard it was would I have just stayed in my 6 figure job before I started out? Not on your life!
If you've got the drive and you're willing to work hard and deal with everything that "is" GA, then go for it!
