How do we account for these cultural losses and non-inventions of Tasmanian society? Flinders Island was even more extreme — that tiny society of 200 people on Flinders Island went extinct several millenia ago. Evidently, there is something about a small, totally isolated human society that causes either very slow innovation or else actual loss of existing inventions. That result applies not just to Tasmania and Flinders, but to other very isolated human societies. There are other examples. The Torres Strait islanders between Australia and New Guinea abandoned canoes. Most Polynesian societies lost bows and arrows, and lost pottery. The Polar Eskimos lost the kayak, Dorset Eskimos lost dogs and bow drills, and Japan lost guns.

Hi Michelle, such a great post! My bread and butter is freelance writing, and I’ve used that to create a full-time income online for around seven years now. I also have an eBay reselling business, and I absolutely LOVE doing that… Working from home can be quite isolating at times, so I love scheduling thrift store trips etc into my working week. It keeps me sane, and reselling is so fun 🙂
If you want to become rich by your 30s, you should be looking at wealth-building opportunities that pay off quicker than traditional long-term investments. One of the best ways to do this is to get into the entrepreneurial game and own your own business. Once you own a business, you have unlimited potential to earn, although you also assume more risk.
If you’ve got gift cards lying around that you never manage to use – maybe you’ve got $50 to Longhorn Steakhouse, but you’re a vegetarian – you can sell them at a discount through gift card exchange sites such as CardCash.com. Once the site receives and verifies the balance on the card (e-cards are obviously handy, but they’ll pay for you to mail in physical gift cards), you can get paid in as little as two days.
There are plenty of books on making money by men who haven't made much. But if J. Paul Getty, who Fortune magazine called “the richest man in the world,” doesn't know how, who does? Here the billionaire businessman discloses the secrets of his success—and provides a blueprint for those who want to follow in his footsteps. And he goes beyond the matter of making money to the question of what to do with it.
Use your credit card’s cash advance feature. Some credit cards will allow you to withdraw a certain amount of cash by using it at an ATM. This can help you come up with cash in a hurry. However, the interest rates on cash advances are usually much higher than the credit card’s usual interest rate, meaning that you will eventually have to pay more.[28]
What happened was that the Samurai, the warrior class in Japan, had been used to fighting by standing up in front of their armies and making a graceful speech, the other opposing Samurai made an answering graceful speech, and then they had one-on-one combat. The Samurai discovered that the peasants with their guns would shoot the Samurai while the Samurai were making their graceful speeches. So the Samurai realized that guns were a danger because they were such an equalizer. The Samurai first restricted the licensing of gun factories to a hundred factories, and then they licensed fewer factories, and then they said that only three factories could repair guns, and then they said that those three factories could make only a hundred guns a year, then ten guns a year, then three guns a year, until by the 1840s when Commodore Perry came to Japan, Japan no longer had any guns. That represents the loss of a very powerful technology.
Look, I know it’s not always realistic to pull these off; I personally wouldn’t bother trying. But if you’ve got a ton of stuff lying around — not outright junk, but stuff you don’t need, like the aforementioned DVDs and kid’s clothes — it’s worth a try. Advertise on Craigslist and put up signs in your neighborhood, then come Saturday haul a table out to your driveway (assuming you have a driveway), load it up with stuff for sale, and take whatever you can get.
Change jobs and employer. Once you've gotten some experience under your belt, consider finding a new job. By changing your environment, you can increase your pay and experience different corporate cultures. Don't be afraid to do this several times. If you're a valued employee, it's also likely your current company may offer you a raise or other benefits if they know you're looking at leaving.
Warren Buffett has long talked about how he focuses on creating value through two "buckets:" The earnings bucket and the investing bucket. If you are wondering how to get rich in your own life, you are likely to find that it is considerably easier to raise your net worth quickly when focusing on both of these, taking the same “double barrel” approach Buffett and his long-time business partner, Munger, have made a cornerstone of their empire.
Have a yard sale to sell things you no longer need. Choose a day or a couple of days to have your yard sale and advertise it in your local paper and online, such as on social media and classified websites. Then, on the day of the sale, arrange the items on tables, blankets, shelves, or in other ways in front of your home. You can arrange the items into groups by price, or price them individually.[3] 

It’s not the sort of online money making opportunity that’s covered in glory, but everyone needs a set of eyes to make sure the numbers add up at the end of the year. Every business and most individuals need someone to help prepare tax returns, especially time or resource-strapped small business owners. The Income Tax School provides an array of training programs that'll certify you with tax prep in as little as 10 weeks, and once tax season rolls around you'll be able to charge an average of $229 per return as a freelance tax preparer with this side business idea, reports CNBC.

Do you enjoy fast food or going into retail shops? Many companies hire mystery shoppers to test the customer service of their stores. A common one is Subway, which hires mystery shoppers to ensure that "Sandwich Artists" are following all the franchise guidelines. If you have time and can travel to different places, this could be a good side hustle.

Even if it’s a mundane task like walking dogs, you could start the next (or only) full-service dog walking and grooming service in your town, where dog owners rave over your business and always refer you to others. You can hire other dog walkers as you grow, and turn your side hustle into a sustainable enterprise. You just have to do the work, and do it well.
