That’s a really tough question, because if you are thinking about it practically, you have to think about what you have that someone would buy. That really lowers the field of what is even viable. People is not a legal option, so selling your family or your ‘body’ and living in prison doesn’t sound practical. Selling items you own that are potential money makers is not practical, like my glass kiln and supplies. Then there is all the stuff you accumulate that no one would pay for, the papers you wrote in highschool, old christmas cards, craft supplies you will never use… you’ll make more money giving it to goodwill and getting a write off.
Find a trade you can master and enjoy, and go for it. My son-in-law is a welder, I bought him a welder several years ago and he is just starting to use it now that he is laid off. A woman found him on Craig’s List and hired him to make a lingere holder for the back of her door. What he didn’t know was that she owns a lingere company, and the piece is going to be used in her next catalog this summer, and she will need a few more pieces—she was so impressed with his work she will be willing to offer the pieces for sale in the catalog as well!!
All because my daughter suggested he try to get a side job and list something on Craigs list…. Serendipity is what will keep you going…
