"I shop therefore I am". 200 words "I shop therefore I am" is one of the most famous sentences of Barbara Kruger, an american artist. It became a point of reflection about our society and our lives. Are we all subject to shopping? In our society don't we have a stop to excesses? Shopping is a fundamental part of our lives but it is dangerous giving it too power. Shopping often works as a substitute for something that we are missing in life. It is wrong thinking about ourselves for the things that we have or what we wear. The worst aspect is that this situation happens without people's realising. For example, new generations can't imagine a life without buying videogames, DvD, clothes (and also expensive clothes), etc. Working is useful to gain money and this implies that we spend it buying consumer goods that we don't need. In brief, we are persuaded to buy by our society and in particular by misleading advertisement. We have to stop us and just think. It is beautiful to can use objects that we like but we hate to obtain a composure and to learn being happy for what we had instead of being sad for what we don't have.
