Some love this career, some hate. Depends on where the luck falls.
Me personally, the first chance I get at a normal job making a decent wage outside of this rat race, I'm gone. I LOVE flying. I can't even describe the feeling I get from flying. But I HATE this career. I'm sick of it, and I've only been in it a bit longer that you (the OP). I hate displacements, I hate commuting, I hate reserve and I especially hate 6 on 2 off reserve blocks where I have to commute.
Would upgrading make life a bit better? Yes, in a lot of ways, but am I willing to do this for another 6 years to get there? I think in another 6 months I'm gonna rip my head off.
I started this month off with 3 uncommutable trips. Two 4 days and one 3 day. I slept in my bed with my wife 3 times in 3 weeks. I love flying...but I hate flying for a living.
