Unfortunately, not everyone loves their job. There are just too many fast food joints in the world for that to be possible. Considering most people work for most of their adult lives towards getting into a specific field, it is kind of assumed that those who are lucky enough to get into their chosen field enjoy it. If you endured years of law school, the endless rejection at auditions, or the trials and tribulations of starting your own business to get into a career you hate, then you're a glutton for punishment. Besides, it's not like those who have fallen short of their dreams are terribly excited to hear how great things are for you now that you've finally gotten that corner office you've always wanted.
