The craziest part of this was I’d wake up in the morning and there would be more money in my bank account, from people who had bought my book overnight. When you think about it, an online store that sells something that’s digital is something that’s open 24 hours a day, 7 days a week, 365 days a year. Using tools, software and systems, you can automate the delivery process so you literally don’t have to do anything to serve that audience. That’s super powerful.
Others may define it more narrowly, but to me, PPC arbitrage basically involves setting up PPC ads (via Google AdWords or similar platform) and directing the traffic that results from ad clicks to a landing page or straight to an affiliate link (which many platforms don’t allow anymore).  The goal is obviously to earn more from the affiliate income than spent on the ad clicks.  You aren’t adding any value, but merely earning more from traffic than what it costs you to generate that traffic.
AbigailP That’s a really valid point, and I totally understand that piling more work on top of your day job isn’t for everyone. Before I started freelancing, I relied only on my day job because I was too drained to focus on other things by the time I got home. I think I’m used to it now, but it’s not easy, especially with chronic fatigue. Having a network to fall back on, or having a Plan B, is still very valuable.
This is mostly passive once you have it all set up, but it does take a lot of work at the beginning. Real estate investing also requires occasional maintenance. Currently, we invest in a couple of rental properties and earn about $500 profit from each per month. You can read more about my rental properties at How and Why I Became a Landlord.

I've got a $185,000 CD generating 3% interest coming due. Although the return is low, it's guaranteed. The CD gave me the confidence to invest more aggressively in risk over the years. My online interest income has come down since I aggressively deployed some capital at the beginning of the year and again during the February market correction. You'll see these figures in my quarterly investment-income update.
Great post Jim. While it is convenient to lump the entire dividend income as one passive stream, in reality, it is several. If you have 30 companies across 10 major industry sectors, each paying you dividends, then you can consider having 30 streams or at least 10 passive streams, from each of the diverse industry sectors. I find this more diverse than relying on rental income from one investment property tied to one location and one good tenant. Your point about website is absolutely valid – will be great to have Ten Factorial Rocks worth 7 figures in less than 5 years as you have done!
IDA’s support for the education sector—including through the General Education Quality Improvement Program and the Enhancing Shared Prosperity through Equitable Services program—has helped Ethiopia expand access to quality primary education over the last nine years. Primary net enrollment rate increased from 79.1% in 2006 to 99.3% 2016. There has also been a considerable reduction of the gender gap for schooling. The ratio of girls to boys for grades 1–8 increased from 0.84 in 2006 to 0.92 in 2016. The gross enrollment rate for secondary school (grades 9–10) increased from 37.1% in 2007 to 44.8% in 2016. Through the Country Partnership Framework, the Bank is working to improve the quality of and equitable access to education to address issues including high dropout rates and low learning outcomes, especially for girls.
Wages received for services rendered inside the territorial limits of the United States, as well as wages of an alien seaman earned on a voyage along the coast of the United States, are regarded as from sources in the United States. Wages or salaries for personal services performed in a mine or on an oil or gas well located or being developed on the continental shelf of the United States are treated as from sources in the United States.
Inspired by you, I started a tax/personal finance a month ago. I figured if it works out, it will create a good side income for me. If not, at least I can use the blog to build my brand as a tax lawyer. Other than that, my current investment portfolio is heavily focused on index funds because of its historical performance and tax & cost efficiency. Right now my dividends income every year is about $14,000. I also have a good amount of unrealized capital gains every year from my investment, though I don’t count the capital gains as my passive income as they are paper gains, at least for now.
Passive income is defined by Wikipedia as “income resulting from cash flow received on a regular basis, requiring minimal to no effort by the recipient to maintain it”. And while the ‘no effort’ part of the definition is very enticing, the truth is that generating passive income requires a massive amount of effort. And this effort needs to be exerted up front and then sustained for months, and maybe even years, until your venture starts returning profits. And even then, you'll have to monitor your income streams to make sure it’s all going smoothly. It's certainly not an easy endeavour, no matter what most people may tell you, and it requires an investment of something far more valuable than money: time. But if you are up for it, then here are 14 ideas that you can use to start earning passive income.
I have been using,”multiple streams of income,” as my mantra during this rough patch. Being an interior designer easily translates into designing other things as well. I have been designing jewelry that is customized in price and style for different stores. I also opened an Etsy shop for my jewelry and for vintage items that I find in my treasure hunting for clients.I am bringing in an extra $1500-$3000 a month, and I am having fun! My first passion is always going to be interior design, and I am thankful for the clients I have!
“Start-up time” required: Poor – Experienced niche site builders will be well versed with outsourcing certain tasks and running through the whole process very efficiently, but when you first start out, it can take a long time to earn your first dollar from a niche site.  Doing research, designing the site, writing content, and doing proper SEO work can all be very time consuming, and the payoff isn’t always something you can rely on.

In the early 18th century, the Mughal Empire declined, as it lost western, central and parts of south and north India to the Maratha Empire, which integrated and continued to administer those regions.[85] The decline of the Mughal Empire led to decreased agricultural productivity, which in turn negatively affected the textile industry.[86] The subcontinent's dominant economic power in the post-Mughal era was the Bengal Subah in the east., which continued to maintain thriving textile industries and relatively high real wages.[87] However, the former was devastated by the Maratha invasions of Bengal[88][89] and then British colonization in the mid-18th century.[87] After the loss at the Third Battle of Panipat, the Maratha Empire disintegrated into several confederate states, and the resulting political instability and armed conflict severely affected economic life in several parts of the country – although this was mitigated by localised prosperity in the new provincial kingdoms.[85] By the late eighteenth century, the British East India Company had entered the Indian political theatre and established its dominance over other European powers. This marked a determinative shift in India's trade, and a less-powerful impact on the rest of the economy.[90]

I knew I didn't want to work 70 hours a week in finance forever. My body was breaking down, and I was constantly stressed. As a result, I started saving every other paycheck and 100% of my bonus since my first year out of college in 1999. By the time 2012 rolled around, I was earning enough passive income (about $78,000) to negotiate a severance and be free.

I think also a very good way to earn a nice passive income is investing in Cryptocurrency, especially in Masternode Cryptocurrencies, which provide a passive income in coins, also those carefully picked coins grow in value, so it’s a double gain! And a great coin to invest in at the moment is GINCOIN, which is the fuel for a really succesful project. Find more at GINCOIN Website: 😉
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.

Capital growth in your portfolio can offset the eroding effect of inflation.  But any capital gains that exceed the overall inflationary effect can be drawn off to augment your portfolio income.  Of course, you must first generate those gains by making thoughtful investment selections.  While allowing strongly growing assets to keep doing that, it is prudent not to allow them to become a dangerously large part of your portfolio lest they go off the boil.  So if you selectively trim profitable positions along the way, you can boost your income.
