I agree if it's sad if you actually hate your job, but rest assured that's not the case for me.
I like my job, it's not too hard, it's not too repetitive, there's lots of different things to do, I can often try out new things, I don't mind being "in the office". Sure, it's not always bright skies, but it's also not like I dread coming to work and I don't sit in my car each morning muttering "I don't want to go, I don't want to go" or something like that.
Frankly, I don't really see myself doing something different and should I ever lose my job, I honestly have no idea what I'd do.
But I'm still happier when I'm not at work, when I can really do what I want. It's not that I don't like doing what I have to do for my job, I just like the "free time" stuff more. To me, it's nothing like the famous trick question which of your children you like best. As far as this goes, personally, there IS a definitive answer, only It's certainly not "love-hate", but "love-love better".
To me there's a difference between liking your job in a "normal" way, and elevating it to some divine reason of your existence.
"There's a difference between knowing you are, and simply being."
