For instance, they offer 50 cents if you upload a picture of a receipt where you bought milk and offer $10 for a picture of a Best Buy receipt. Of course, it makes no sense going out and purposefully buying products with the highest rebate, yet it won’t take much of your time taking and uploading pictures of things you typically buy and stash some extra cash by the end of the month.
Selling blood….there are very few companies that buy your blood. #1 reason being MANY people willing to sell their blood are not the type of people you want to receive their blood, ie drug addicts (not everyone). And if you can find a company willing to buy your blood you can only give it every 56 days (for whole bood). The most common blood product that is bought is plasma and you can only do that every 28 days (in New York state …which won’t buy blood anyways).
I advocate for the Tim Ferris, multiple income stream strategy. It’s important to have a diversified portfolio and automatic income streams that supplement your basic income earned through work. Selecting the best investment and income streams requires a person do the research, but very basic strategies can be employed that grow the money nest. I think the article is right to say it’s better to earn rather than save more than you spend, because saving money can depend on very specific contexts, while earning money tends to be more predictive. Good article.
