Struggle

When you take water away from fish, fish will die. I have this familiar feeling right now. Why? As you guys know, I am studying commerce instead of film now, such as microeconomics, macroeconomics, corporate finance,etc. Don't get me wrong, I enjoy facing new challenges and learning new stuffs. But, If you were me and faced tons of different formla, model,etc, you would want to pull your hairs out as well.
