Selling Garbage?

Actually i hate it, but my friend from campus inspired me to do that. He's able buy his own pc just from selling junk. he come to some office and asking for lastmonth/yesterday newspaper, failed print paper, and ex-box product. Or come to some caffe and asking for junk from plastic ex-soft drink/milk. that how he earn extra money when he was college student. Now i'm working in office and ask the officeboy sorting the junk from it [usually officeboy throw it to junk box]. i don't want the money, but i know officeboy fee is not so big, i hope it can be some extra for them.

I collected cans, plastic bottles and newspapers. I have them in piles and bundles in my store room. The man will collect them once every three month. I'll get around MYR 40.00 and I can buy presents for my mom. It helps to save environment and I can get extra money.
