First thing i would like to point out, don't ever tell us how young you are. Some people on here don't believe in helping teens because they don't think they are able to do anything.

Have you heard of GPT (Get Paid To) program? PTC - Paid To Click Paid To Read Email (Not Suggested) Paid To Review. Paid To Survey And a similar to it. If you haven't try it before, just go to internet4freemoney blog. But only PTC report available for now. *TIP - Invest to make more money.
