One of the key principles of money is ‘opportunity cost.’ It means that when I buy something, I have to give up something else in return. We think we buy because we need something, but we often forget that we could buy something else instead. We rarely consider ‘opportunity cost’ when making a purchase. We do not compare other values against our needs. Buying something means giving up something else, but we often don’t realize it. When we spend money, we should also consider the ‘opportunity cost’; yet, in reality, we aren’t trained to do so. By making a purchase, we bypass the value comparison that may not offer any additional benefits. Maybe it’s because we lack knowledge, or perhaps the idea isn’t appealing. - Joseph’s “just my thoughts”
The essence of cubism is to get rid of the viewpoints of the object. Cubism shows us the inside and outside, top and bottom, front and back of the object simultaneously with 2D reorientation, as a result, the observer's viewpoints disappear altogether. Finally, cubism makes us see the whole of the object. If you want to see the real world, throw away your viewpoints completely. - Joseph's "just my thoughts"
