One starting point for understanding economics is that everybody wants stuff. Economists study consumption, or noming.
Our first character, Gustav von Om Nom, loves noms. If you do not love cookies as much as Gustav, there must be something you really want. *iPhonomnomnom*

When I recently brought home donuts, my roommates decided we should fry them. Yes, donuts have already been fried. Double-fried donuts. Om Nom Nom.

This illustrates our “convex preferences.”
Our household prefers more food to less food. So, we would rather have 20 pounds of food in the fridge than 15, because 20 15.
However, our happiness is not just a function of the pounds of food in our house. We would not want ONLY donuts, even though we like them. We prefer to consume food in combinations. For example, a salmon dinner followed by a double-fried donut.
So, we would chose 15 lbs of a mix of foods instead of 20 lbs of just donuts.
