The other lesson that I would like to draw from history concerns what is called the optimal fragmentation principle. Namely, if you've got a human group, whether the human group is the staff of this museum, or your business, or the German beer industry, or Route 128, is that group best organized as a single large unit, or is it best organized as a number of small units, or is it best fragmented into a lot of small units? What's the most effective organization of the groups?
They don’t even have to be your bottles: Plenty of people are too busy or lazy to bother returning a six-pack worth of beer or soda cans for 30 cents and simply leave them out for curbside pickup. It may not be trash day in your neighborhood, but it surely is somewhere. Fill up a 50-gallon trash bag with cast-off cans, and you can redeem them for about $12 – it’s just a start, but you can do it again and again, and all it takes is time and hustle.
Tenants sounds good, but can be a toxic problem as I recall before of one studying Religion and Ministry somewhere and claimed to be clean and laid back, but came to light by another tenant he stayed with to have a bad temper, bad attitude and never clean up his own dishes and have his stuff scattered in living room without first discussing with his roommate and always asked other roomie for rides and money as a moocher and would get pushy if his roomie refused as unable to at times.
If you’ve got expertise in a certain area, package up your knowledge into an online course and sell it. This has become a very popular business model for online entrepreneurs over the past several years. The two big websites that are used to sell online courses are Udemy and Teachable. Check out this awesome article by Regina on How to Create an Online Course that Sells.
I’d say an interesting thought to add would be an idea suggested by Mark Cuban a while back on his blog. It was basically the idea that you’re not necessarily saving money so that you can invest slowly and retire comfortably, but that you were saving every possible penny, at every moment, so that when an actual fantastic opportunity came around you’d have money to invest.
There are a variety of online lenders out there, and if your credit is fairly good, you can apply for a personal loan online and be approved almost instantly. The money will still take a few days or even a week to hit your account, and the interest rate will be higher than, say, a home equity loan. But a personal loan from a reputable company — and be careful, for some online lenders are little more than payday loan shops online — beats credit card debt for a couple of reasons: Installment loans are better for your credit than revolving credit card balances, and even a 10% interest rate is preferable to what you’d pay for a cash advance.

While it is possible to make a lot of money while working for someone else, the truth is that you should mind your own business. Start and grow your own business, no matter what it might be. Identify what you're really good at, and develop the skills into a business that you can expand over time. Don't look for instant payouts or overnight riches. The reality is that it's going to take time, so you might as well start now.
Companies like Uber and Lyft offer a great opportunity to make some quick cash. You'll need a clean driving record, a fairly new car and the authorization to work wherever it is that you live. If you have all of those things, you can work when it's feasible for you, whether that's in the middle of the day during rush hour, or in the wee hours of the night on a weekend. The choice is yours.
As you start regularly putting out content, you’ll hopefully start to build a bit of an audience. But to start seeing real money from YouTube you need to market your videos elsewhere. Share your channel on Twitter and Facebook. Distribute videos anywhere else you can think of. Also, interact with comments and build a community around the videos you’re making so people will share it with their friends.

You know those top-down cooking or craft videos you just can’t seem to get away from these days? There are people out there making a living from them. 78% of B2C companies depend on user-generated content, like those videos, for their marketing campaigns. You can sign up as a creator on a site like Darby Smart and potentially work with brands like Nordstrom, Mattel, and BarkBox. Or, learn how to master PPC advertising and you can use the content to build your YouTube following and monetize through ads and views.

Great message, Jeff. When I look at big goals, or even incremental goals, I like to break them down into bite size bits. Earning $100,000 a year seems difficult in many situations, but it seems easier when you break it down to $8,350 a month, or roughly $280 a day. Sure, that is aggressive for many salaries, but there are many ways to fill the gaps with side income, owning a small business, consulting, freelance work, etc. The same concept works for any number or goal you want to reach. Find out where you are, and what it will take to reach the next step. It’s much more attainable when you make incremental goals.

So these stories of isolated societies illustrate two general principles about relations between human group size and innovation or creativity. First, in any society except a totally isolated society, most innovations come in from the outside, rather than being conceived within that society. And secondly, any society undergoes local fads. By fads I mean a custom that does not make economic sense. Societies either adopt practices that are not profitable or for whatever reasons abandon practices that are profitable. But usually those fads are reversed, as a result of the societies next door without the fads out-competing the society with the fad, or else as a result of the society with the fad, like those European princes who gave up the guns, realizing they're making a big mistake and reacquiring the fad. In short, competition between human societies that are in contact with each other is what drives the invention of new technology and the continued availability of technology. Only in an isolated society, where there's no competition and no source of reintroduction, can one of these fads result in the permanent loss of a valuable technology. So that's one of the two sets of lessons that I want to draw from history, about what happens in a really isolated society and group.         
Become a babysitter if you are good with children. There are websites that will connect you with people who need a babysitter. To get hired by people who do not know you, it will help to pass a CPR class, or to have a special talent or expertise for entertaining children. However, you might be able to make money more quickly just by babysitting for people you know, or by having friends refer you to others who need a babysitter.[13]
The result is that Japanese food-processing industries are not exposed to domestic competition, they're all local monopolies, they're not exposed to foreign competition, and they don't learn the best methods in the international trade for producing food. And the result is that, in Japan, Japanese beef costs $200 a pound. My wife and I had heard about that before we went to Japan, but what we did not realize until we were brought into a supermarket by my wife's Japanese cousin is that chicken in Japan costs $25 a pound. The reason the Japanese can get away with that is that Japanese chicken producers are not exposed to competition with super-efficient American chicken producers.         
Don't put all your trust in Social Security. While it's a good bet that Social Security will continue to work for the next 20 or so years, some data suggest that if Congress doesn't radically alter the system — either by raising taxes or reducing benefits — Social Security won't be available in its current form. It is probable, however, that Congress will act to "fix" Social Security. In any event, Social Security was never designed to be the only resource for retirees in their later years. That makes it all the more important that you save and invest for the future. [1]
I’ll be more than a millionaire, I don’t doubt it at all. The hardest part is starting your way up the curve, since that’s when the snowball process of compounding takes the longest to kick off. Once you reach a critical mass, the last… say… third or fourth of the journey will be relatively easy. If you’re in the right investment allocation, the real question is how soon can you make it to $750,000 in net worth? Or how soon can you start bringing in income from a second investment property? No, friends, a million is not far off at all…
That outcome, of Germans having their local beer loyalties, is reinforced by German government law. The German government makes it hard for foreign beers to compete on the German market. The German government has so-called beer purity laws. The German government specifies exactly what can go into beer, and not surprisingly what can go into beer is what German breweries put into beer, and it's not what American, French, and Swedish breweries like to put into beer. So it's difficult for foreign breweries to compete on the German beer market. The result is that German beer is not exported very much. Any of you who like to buy Lowenbrau in the U.S. should look at the label in the supermarket: your U.S.-bought Lowenbrau is not brewed in Germany, it's brewed on license in the United States with American productivity and American efficiencies of scale.
Not quite ready to start your own blog, but still like the idea of getting paid to write? You may want to consider trying your hand at freelance writing. Many bloggers and website owners are willing to shell out some serious cash for high quality writers. In fact, Holly Johnson from makes over $200,000 per year from freelance work! And she has a course that teaches others how to do the same.
