I love what I do.
I couldn't think of anything more fun to do, honestly.
Of course there are always things about the job which have a negative effect on you, but such is life. I could think of MUCH worse fates.
As for those who say "it's called work for a reason", I find that's a cope-out and you just haven't found the right job for yourself. You CAN enjoy work if you find something that really interests you.
Note: I've been to jobs which I've ended up hating with a passion. Couldn't wait to leave.
