I think that everyone can divide all advertising products and services into useless ones and useful ones. It is like looking through an information desk when you pay attention to those messages that interest you. Take me for example, I do not like jewelry. It does not mean I do not have it at all, I have a couple of inexpensive rings as gifts from my parents. I just think, people pay too much attention to that stuff. I believe it is the result of mass advertising. Every day when i am watching TV, listening to the radio or reading the paper i notice many ads about getting an expensive ring, chain, necklace or earrings. From my point of ,view these kinds of advertising contaminate people's minds. In this ,case you are encouraged to buy things you do not really need. They make you believe you need such products in order to succeed or be happy.
