There are two types of things that we put money into; the things that we need and the things that we don't. The former represent our physical needs and the latter our spiritual needs. Food for the body and food for the mind. We need to eat, but we don't need to see a movie. We need a house to live in, but we don't need a house of worship. We need a car to get to work, but we don't need a painting on our wall once we get there.
