I disagree, I first learned economics when I was about 14-15 years old and it is a total new world for me. New knowledge, new something, but it really pique the interest of all of us in that very room. Everybody is listening and participating during lectures, and it is quite fun. Besides that, economics can be very boring in that phase so I didn't study at home, and just at the school.

Now I'm in college, I'm totally aware and knowledgeable about the economics which is now very interesting cause I know the benefit I can attain from learning it, and the knowledges and wisdom that I can apply in real life. Im not a business major, yet I can tell you that I myself am learning economics aside from my class.

Ergo, learning economics is about the phasing, and modes of learning that suits yourself. You shouldn't force yourself to learn this things cause it will not be very beneficial for you, for you have many other subjects that must be passed.
