It varies. I've had lots of different jobs. Some I enjoyed until the day I left. Others I hated after the first hour in the door.
Though I can't remember too many that I LOVED. I can remember some I didn't mind, some that were enjoyable from time to time. But the one thing about work is it's almost always work.
As far as the 2 jobs I have now, one is a kitchen manager - don't like it, lot's of stress, high heat, high intensity. But it pays well and is occasionally fun.
My other job is an overnight security officer (working right now). And though this is much more relaxing, it's almost never fun, and very very boring.
I would have to say that I never loved either of them.
