Every single one of us has/had a passion for flying. If you are miserable at work, then you are gonna bring that funk and bad attitude home, I know this because my father hated his job. My mother is a flight attendant, growing up with her gone made me appreciate her time at home, but she also took me with her on some trips which exposed me to the airlines early on in life. I loved it, and was always excited when my mom came home with cool stuff from around the world, I wouldn't trade it for anything, she taught me to be self reliant and I can't thank her enough for it. Bottom line, my mom came home happy because she loved her job, my dad came home miserable, you tell me what's better to be around as a child?
This job isn't cut out for everyone, but sometimes I think the spouses we pick are not the right ones for us either, we're just too stupid to realize that and blame it on everything else, including our airline jobs..
