The objective would be to recognize, if I really need a product, or if I just want it. Nowadays the limit between the need and desire became so blurry. We no longer make the effort to make the difference between these two notions. And it's a serious issue because, our current society has become an overconsumption society, values such as resiliencence have disappeared. Human beings, no longer know how to abstain theirselves, indeed, the desire for a product has become the only reason to buy it, and our need for this object has completely passed in the background. We are in a society, where the desire is the sole motivation for consumption. And in the end this society, will end up to become autophagic.
