It seems to be the dream of any teenager — to sell the mess in their room. British artist Tracey Emin actually did it. In 1999 she had spent several days in bed when she was deeply depressed due to hardships in her relationships. Later she sold the installation made of trash and leftovers at an auction which she called “My Bed” to Charles Saatchi for $150,000. The man turned around and resold this item as a symbol of suicidal depression for $4 million.
