A few people who started their own YouTube channel when the video-sharing site was in its nascent stage are now millionaires. Now that YouTube has become immensely popular with hordes of people running their own channels, making a million dollars is considerably more difficult, but earning a respectable sum of money is still possible. As always, you'll need to find a niche that isn't yet saturated and focus on making engaging videos around it. Once you start raking up views and subscriptions, the money will start flowing in with minimum effort on your part.
Wouldn’t it be nice to earn money while not working? That money is called residual, or recurring, income. It's what can happen after you put a lot of time, effort and sometimes money into a job to continue to get paid for the work months or years after it's done. (Salary jobs are part of linear income. This income is directly related to the number of hours you work. If you work 40 hours, you get paid for 40 hours of work.) Once you set up your business to earn residual income, you continue to make money while doing other things – maybe even starting a new business to generate more residual income!
My personal finance blogs were started with $100, but you can start a blog with $20 if you buy hosting on a monthly basis. That’s 4 Starbucks coffees or 4 packs of cigarettes many paycheck to paycheck people do find a way to buy. After six months of HARD work, my first site started generating $2,000 a month, and today, those three sites generate over $5,000 a month, while all I have put in was hosting for $100-ish every year each, and a website redesign for under $1,000 after three years. Freelance writing and translation jobs are also a sizable part of my income that did not require any upfront investment. Investing $10 a month in index funds is also a realistic way for many to build yet another income stream.
Now, all that said, if capital (savings) grows faster than the growth of the economy, those with savings will see their wealth grow at a faster rate than those who rely on the growth of their income. While this is not an extension of Piketty's argument (you can't take an idea that applies to a population and a whole economy and boil it down to the individual like this), it's not an unreasonable conclusion to take and apply to your own life. (Piketty does talk about this on an individual level, but says it's more impactful for billionaires vs. millionaires – though we have limited data into individuals)
However, the RI-based approach is most appropriate when a firm is not paying dividends or exhibits an unpredictable dividend pattern, and / or when it has negative free cash flow many years out, but is expected to generate positive cash flow at some point in the future. Further, value is recognized earlier under the RI approach, since a large part of the stock's intrinsic value is recognized immediately – current book value per share – and residual income valuations are thus less sensitive to terminal value.[5]
If you're a graphic designer or even an amateur artist, there are plenty of sites which will pay you for sharing your artwork. Sites like Etsy, Zazzle, and The Souled Store allow people to add their designs to T-shirts, phone cases, mugs, posters, book covers, and more. If and when these products are bought, the sites then pay a commission to the contributing artist.

Nice list. What keeps my family from getting more streams is the time it takes. I would actually be willing to work part time in medicine and make less money with a side-hustle just to keep things fresh and prevent burnout. That requires some degree of FI and some time to read about the new endeavor. Maybe when my kids are both in school, we we see. Until then, I’ll keep reading your posts for ideas.

I cut back on medicolegal work to free up time and reduce stress. I spend most of my time on medical directorship work and clinical practice. Free time is spent on exercising, travel, time with family, and blogging. I spend virtually no time on the other income streams at this point. Getting the plate spinning can be tough but then the momentum keeps them turning.

If you’re into antiques, for example, you could check out garage sales for hidden deals then capitalize on your knowledge to turn a profit. Perhaps you’re into video games, specific brands of clothing, or something else. Whatever it is, with a little research, it’s possible to turn your knowledge into cash with an eBay store. Best of all, you can sell from the comfort of your own home.

For those of you who don’t want to come up with a $220,000 downpayment and a $900,000 mortgage to buy the median home in SF or NYC, who don’t want to deal with tenants or remodeling, and who wants to not do any work after the investment is made, check out Fundrise. They are my favorite real estate crowdsourcing company founded in 2012 and based in Washington DC. They are pioneers in the eREIT product offering and they’re raising an Opportunity Fund to take advantage of new tax favorable laws.
Good suggestions. I have many of these. One word about the “app” idea. I had a great idea related to personal taxes that I tried to get off the ground with my accountant as a partner. I would say it’s difficult to do this unless you have a coder on your team. Hiring someone is not really viable financially unless the app is simple. When we finally got the quote for a coder to write what we wanted (and after doing lots of mock ups ourselves and getting a demo for investors) the estimate was about 750k just to really get started.
The bottom line is, it’s smart to have multiple income streams no matter who you are. Why? Because the more ways you can earn money without compromising your integrity, the better off you’ll be. And if you’re self-employed, having multiple income streams is almost essential. Not only will you enjoy a higher income, but you won’t go broke if one stream ends out of the blue.
But first, let’s about talk passive income! What is passive income? There are many different definitions out there, but mine goes something like this: Passive income is all about building online businesses that can work for you, that allow you to generate income, and grow and scale, without a real-time presence. In other words, you don’t trade time for money. You build something up front that can continue to work for you over time.
Leveraging the internet to create, connect, and sell is something every creative person should attempt to do. The only risk is lost time and a wounded ego. You can start a site like mine for as little as $2.95 a month with Bluehost and go from there. They give you a free domain name for a year. Forget all the add-ons. Not a day goes by that I’m not grateful for my site.
A lot of people don’t even know about my life insurance business, but it’s a huge part of my success. Like my other big projects, however, I started it to help people. Over the years, I’ve seen so many people who are uninsured or underinsured. For whatever reason, they don’t understand the importance of life insurance. Worse, they don’t understand how affordable it is for the average family.

Leonardo da Vinci is another example of someone who was a "wide achiever," in the words of Roman Krznaric, author of "How to Find Fulfilling Work." Da Vinci was alternately a portraitist, an inventor, and a scientist. Krznaric says that in light of decreasing job security today, spreading yourself among several different jobs, as da Vinci did, is probably a smart thing to do.
How do you return $103,000 a year in dividends and interest on a total investment of about $ 1.2 million in stocks and bonds? Makes no sense to me. Am I the only one befuddled by this? You even state a high percentage of those pay no dividends. What am I missing? A reasonable return on income generatimg stocks and bonds is closer to 4%. Even grossing up for net tax effect of munis does not get to anywhere near these returns,

I have not. While I am intrigued with the possibility of making online income, it seems to be less passive then how I want to spend my time. Regarding your blog / site, you have done quite well for yourself. However, you have to keep pumping out content or your site would eventually go out of business. That sounds like more of a commitment then I would want. Regarding your book sales, it is probably relatively passive now, but certainly was not when you were writing the book. Now if you love it, great. Just not for me.

I just started out with Affiliate Marketing (idea # 8) and it is not as easy as people make out to be. For me, the hardest part so far, is learning Search Engine Optimization (SEO) and driving traffic to my website. I’m only 3 months into it, but I am confident that the site will begin to generate some incom., I have to give it 6-9 months, so we’ll see.
Establishing residual income allows you to accumulate wealth faster, have a more flexible lifestyle and maintain a diverse financial portfolio. As with any successful investment, hard work is required. With residual income, however, that work tends to be upfront. Once your revenue stream is established, the work and time involved is significantly lower than active income sources. With residual income, you’ll secure funds for your future, have a better idea of where you stand financially and enjoy peace of mind knowing you’re maintaining lucrative, long-term investments.  
One of the earliest ideas on the circular flow was explained in the work of 18th century Irish-French economist Richard Cantillon,[2] who was influenced by prior economists, especially William Petty.[6] Cantillon described the concept in his 1730 Essay on the Nature of Trade in General, in chapter 11, entitled "The Par or Relation between the Value of Land and Labor" to chapter 13, entitled "The Circulation and Exchange of Goods and Merchandise, as well as their Production, are Carried On in Europe by Entrepreneurs, and at a Risk." Thornton eds. (2010) further explained:
You aren’t going to get rich overnight by creating YouTube video tutorials, but there’s a lot that you can do with YouTube videos to generate passive income online. The first thing that people think about when it comes to YouTube videos are the Adsense revenue streams. However, don’t get your hopes up unless you expect to have millions of views for that video.
Well, first, you shouldn’t buy into the hype. Don’t allow these network marketers to sell you this so-called dream. It doesn’t quite work that way. You won’t get rich by sending out emails or “driving traffic” to some squeeze page. It will be nominal at best, and when you set your hopes high, you’ll end up getting discouraged like the others. In order to “truly make it” as an internet marketer, you need a huge following. We’re talking tens of thousands or hundreds of thousands of email subscribers. Yes, that many.

We have decided to invest in 2 ETFs, a multi asset allocation ETF (Fixed Inc, alts and div paying equities) and a preferred stock ETF. This will cover almost 45 percent of our deficit. We will be extremely diversified, can access the markets at a very low cost and the investments are liquid. On this pool of $, we have no plans to invade principal unless the investment grows by 20 percent, which we think is unlikely given the characteristics of the investments.

When most hear the term residual income, they think of excess cash or disposable income. Although that definition is correct in the scope of personal finance, in terms of equity valuation residual income is the income generated by a firm after accounting for the true cost of its capital. You might be asking, "but don't companies already account for their cost of capital in their interest expense?" Yes and no. Interest expense on the income statement only accounts for a firm's cost of its debt, ignoring its cost of equity, such as dividends payouts and other equity costs. Looking at the cost of equity another way, think of it as the shareholders' opportunity cost, or the required rate of return. The residual income model attempts to adjust a firm's future earnings estimates, to compensate for the equity cost and place a more accurate value to a firm. Although the return to equity holders is not a legal requirement like the return to bondholders, in order to attract investors firms must compensate them for the investment risk exposure.
Of course, the total economy is much more complicated than the illustration above. An economy involves interactions between not only individuals and businesses, but also Federal, state, and local governments and residents of the rest of the world. Also not shown in this simple illustration of the economy are other aspects of economic activity such as investment in capital (produced—or fixed—assets such as structures, equipment, research and development, and software), flows of financial capital (such as stocks, bonds, and bank deposits), and the contributions of these flows to the accumulation of fixed assets.[4]
Department C has earned $142.5 million residual income as compared to $40 million earned by department P. Residual income allows us to compare the dollar amount of residual income earned by different departments. Since the residual income in both cases is positive, we conclude that both have met the minimum return requirements. However, with residual income is not easy to compare performance.
3. Rent - Being a landlord is fabulous. You get rent for the rest of your life on the asset that you have created. This type of income also can grow if your property is good, well maintained. The growing income is a hedge against inflation. If you can earn rent to pay for your living expenses every month, you can be very close to achieving financial freedom!
You need to decide which machines you want to run, get the necessary licenses to operate them (you're selling items so you need to get sales licenses and whatnot from your state), buy the machines and a truck for the items in the machines, find a supplier of the products, and then finally you can secure locations. Finally, you need to service them periodically or hire someone to service them.
If retirement is a goal of yours (and who doesn’t want to retire someday?!?), it’s important to learn how to start investing. In fact, funding your retirement accounts should be at the top of your list. While these accounts won’t help your immediate situation, by stashing cash now, the residual income they create should help propel you through your golden years.
