Circumstances conspire against you and life is full of traps. If it wasn't for very helpful parents to mind my child when I am away for 3 to 5 days I would have to give up flying. My ex having her struggles to cope with life. My point being, have your better half support you on this journey of yours. If not, be ready to give it up. Or your dream will turn into a nightmare. Sounds dramatic? Possibly. But I am sure many can say "been there, done that". Depending on who you end up flying for, you could be spending up to 2/3rds of your life in hotels. Or in a crash pad. Away from home, regardless. Long haul a tad better, but you'll be jetlagged instead.
The flying, the crew, the irregularities is grand. Not much to say there.
It's tough on families. It's a young man's game.
