Then, it hit me! I enjoy understanding how my business's money circulates. Why not major in economics?---I suggest saying this in a different way, too. No, you should go into greater detail about the depth of your contemplation. You need money to survive, so you should learn economics, and this will enable you to do anything you want to do as a freelancer. But I don't think you should say "Then it hit me" or "why not..."
When deciding on the major, I had to consider what I could attain from a career in economics other than wealth.

Okay, how about citing a few books or articles. Have you studied Keynes? Show that you are already fascinated. Google this: freakonomics (it's a recent book)
