Good luck managing your mortgage and investments without having proper economic knowledge 
Well, my mother has a great financial mind and she wasn't formally educated in economics (or beyond year 10, for that matter). You might love money and economics, but by relating economics to financial concepts like mortgage and investment is only hurting your cause of propagating the loveliness of economics. Of course economics has uses for monetary purposes, people already know that, but I am trying to point out here that economics is not a study that is restricted to commerce (just as econometrics is not a study restricted to economics).
When entering university, I had no idea what to expect from Commerce, but I had this feeling it was a pretty shallow and empty course that was focused on money, and how to manipulate it to get more (I thought engineering was the more appealing path - use my expertise to get money, rather than just manipulating it). I extremely underestimated the scope of economics and commerce.
