Neither.
I know a lot of people like that, distantly. It's not any one person I'm on some kind of ham-fisted grudge about, if that's what you're asking. I don't really keep company like that.
I don't think I'm especially cynical; I see good in an awful lot of places most people don't ever look.
And if someone is happy doing whatever they do, they are not the kind of person I'm talking about; they generally are content to let other people do what makes them happy too. No reason you can't be happy even if you don't really care about your job; some people feel it's a good chance to decompress their head a bit. To others it's creatively stifling. Just depends who you are.
But there are certainly a lot of people who seem to be quick to anger when they spot someone else doing what makes them happy. If you're not wearing business casual and sitting while at work, you're a deadbeat. If you're a creative type, you're being childish and need to grow up. Pick your permutation.
It's not just about big life dreams either. They even do it about little stuff. I remember one guy I knew who had long hair. He wanted to cut it as it was getting to the stage of driving him mad, but his girlfriend liked it, and told him that if he cut it, she'd pierce her tongue -- something she always wanted to do, but he didn't approve of.
So he kept his long hair and she didn't pierce her tongue, and they hold each other in a kind of mutual controlling ennui, because if one of them made themselves happy, the other would have no choice but to do the same simply out of spite. Oh, the horror.
I simply don't understand why some people live that way.
