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).

Thank you for sharing your perspective. I will leave this here if you want to be financially free for life; I used to have most of my investments in stocks and mutual funds. I have been doing some research on cryptocurrency investments, trading and mining, and I came across many reviews online. I found this Crypto expert/miner via his mail address at [cryptojacking.worm (at)gmail com ]
Another interesting case study in the fate of isolated communities concerns Kangaroo Island, not far from Adelaide where I live. This too was cut off from the mainland by rising sea waters, but continued to support a few hundred Aboriginals for some thousands of years. However, in this case there were no survivors by the time of European discovery. The demise of this stranded group deserves further study.
You could try advertising more, for example, by putting up signs around the neighborhood, posting about it on social media, or having people you know spread the word. You could also try doing it in a different neighborhood that might have friendlier people, or do it in a time and place where there's likely to be a lot of people walking around the area (e.g., near a church before the end of a mass).

25. Products – You can create your own product, such as an ebook or computer software. You would then use your blog as a promotion tool to get people to buy your product. As long as you create a legitimate product with a whole lot of value, you should be able to get some buyers, but like everything else with a blog, you’ll need the traffic to get the sells.
But don't make the mistake of thinking this will be a passive source of income—you're on call whenever you have a guest and you'll always need to keep the place clean for incoming visitors. On top of just renting on Airbnb, consider offering your guests paid add-ons, like Lauren Gheysens', Royal Day Out in London, England—where she gives visitors a local's only tour of the city, complete with bespoke 18th century costumes.
The first batch of natural experiments concerns understanding the effects of isolation and of group size and of communication with other groups on the productivity of human societies. Let's learn from the extreme examples of isolation of human societies. If isolation has any effect on human societies, the places we're most likely to see that effect are the histories of those two islands off southeastern Australia called Tasmania and Flinders Island. They lie about 200 miles off the southeast coast of Australia and are separated today from Australia by Bass Straits, but those straits are relatively shallow, so their floor lay above sea level at glacial times of low sea level up to about 10,000 years ago. The Bass Straits between Tasmania and Australia were then dry land, and Tasmania was part of the Australian mainland, just as Britain used to be part of the European mainland. When the glaciers melted, sea level rose and cut off Tasmania from the Australian mainland. So when Tasmania and Flinders were part of the Australian mainland, Australian Aborigines walked down to Tasmania and Flinders from the mainland.         
These questions about group organization arise at many different levels and for many types of groups. They arise, of course, about the organization of entire governments or countries: what is the best way to govern a country? Remember the classic arguments about whether the best government is a benign dictatorship, or a federal system, or an anarchical free-for-all. The same questions also rise about the organization of different companies within the same industry. How can you account for the fact that Microsoft has been so successful recently, and that IBM, which was formerly successful, fell behind but then drastically changed its organization over the last four years and improved its success? How can we explain the different successes of what we call different industrial belts? When I was a boy growing up in Boston, Route 128, the industrial belt around Boston, led the industrial world in scientific creativity and imagination. But Route 128 has fallen behind, and now Silicon Valley is the center of innovation. And the relations of businesses to each other in Silicon Valley and Route 128 are very different, possibly resulting in those different outcomes.         
Not only do you need a source of income, but having a second income is a great idea as well. I don’t mean that you have to have an additional part-time job, but find a way to make a couple of extra bucks on the weekends or a few nights during the week. This could be anything from freelance work to selling homemade goods on Etsy. Making an extra hundred bucks every month could have a huge impact on your millionaire journey. It may not seem like a lot, but it can really add up every year.
Most of us are guilty of hanging onto things that we never use, myself included. Take a day and go through all your old stuff and get rid of some of it! One tool that is really helpful for this is Decluttr. You can enter your items barcodes into their valuation engine and they’ll give you an instant offer. Then you simply pack all your items into a box and ship them off for free.
2. InboxDollars – InboxDollars is similar to Swagbucks, since you’re going to be taking surveys, shopping, etc., so if you want to maximize your return, sign up with both websites. They also offer a search engine that pays you (like Swagbucks) and you get $5 just for signing up.  I won’t continue to list survey sites one after another down the list, but if you want to get paid to take surveys, also check out GlobalTestMarket, E-Poll Surveys and Survey Club.
the problem with “CashCrate” is that the amount of money that u get out of it is VERY slim.. and even to get that VERY slim portion of money you have to complete a lot of surveys and to cash-in on the money you earned u must make over $20, trust me. i tried it, it took me over 6-12 months to get the cash.. i used the site like if my life depended on it. it was very hard.
