If one really enjoys the work one will not treat the work as _work_, but rather something that is FUN - - EXCITING - - REJUVENATING
But it's not. An exhausting activity doesn't become any less exhausting just because you enjoy it. You need downtime for maintenance, no matter how much you might not want it.

From office politics to micromanagement to inane performance metrics to managers who make it perfectly clear that they see themselves as feudal lords running their little fiefdoms for the enlargement of their egos and couldn't care less about efficiency, a modern workplace is set up precisely in such a way as to discourage professional pride and encourage cynical resignation. That's not particularly surprising, since the people who designed it had no better models of organization to draw from than said feudal fiefdoms, which were not set up for efficiency but for suppressing peasants by crushing their spirits.
Some people can shrug off the lingering stink of dung ages and excel, some can't. But something is very wrong when it takes an exceptional person just to not view your primary means of accomplishing something as soul-crushing drudgery. Most jobs aren't inherently that bad, and most people aren't really content to merely consume. Even places like 4chan spin around creativity, crude as it might be. So why does the average peon dream of winning it big and forever escaping the need to work for a living?

Now that is the trillion-dollar question.
