Why Study Economics - It's Fun!
Because I enjoy the topic. That's an absolute must to study economics. I wouldn't suggest anyone study economics if they do not enjoy at least some of the topics involved. Like anything in life, you get out of studying economics what you put in. Don't study economics because you think it's the route to a high paying job - you'll likely hate the program so much that you drop out (or fail) and if you do end up graduating, you might find you don't like the jobs your degree has made you qualified for.
That being said, I don't think it's a requirement that you love every aspect of the discipline. I quite enjoy microeconomics, industrial organization, and game theory. Econometrics? Not so much. As an undergraduate there were enough topics I liked that it helped me get through the ones I found difficult or did not really care for.
