The thing is, I’m not talking about buying brick-and-mortar buildings. I tried that many years ago with my father-in-law, and with devastating results. We tried to buy a duplex once, and the deal fell apart after we realized we weren’t really prepared for the purchase. I secretly wanted to become a landlord, but at the same time, I knew it wasn’t for me.

Millennium Development Goals Report 2007 . The report importantly notes that As high as this number seems, surveys show that it underestimates the actual number of children who, though enrolled, are not attending school. Moreover, neither enrolment nor attendance figures reflect children who do not attend school regularly. To make matters worse, official data are not usually available from countries in conflict or post-conflict situations. If data from these countries were reflected in global estimates, the enrolment picture would be even less optimistic.
If you watched the video, he goes into a discussion about shocks (about 8 minutes in) like bad investments but how they don't really matter as much if r (rate of return) is greater than g, the rate of economic growth. If r = 5% and g = 1%, then you can lose 80% (the difference) and still be ahead because the return on the remaining 20% has paced with economic growth.
Do you know of a successful business that needs capital for expansion? If so, you can become something of a small-time angel investor and provide that needed capital. But rather than offering a loan to a business owner, you instead take an equity position in the business. In this way, the business owner will handle the day-to-day operations, while you will act as a silent partner who also participates in the profits of the business.
Came to the U.S. as an immigrant in 1968 from a poor Asian country with only $100 in my pocket. Took advantange of 401-K savings plan by contributing 10% of my pay. My employer matched the first 6% savings (50 cents/dollar saved). Did not know anything about investment so 100% of 401-k money was invested in index 500. No other savings except 401-K. Retired in 1999 at 55 years old with about $1.2 million in 401-K and $450,000 lump sum pension which I rolled over to IRA. I invested this money in bonds and only buy equities (small cap index) whenever value drop to at least 50% of its high. I made a lot of money by investing in small cap index (ticker, IWM). Because of the risk involved, I don’t buy individual stock.
If you have a spare bedroom, you can find a roommate or list the space on AirBnB for travelers. Having a roommate is the more passive of the two, as being an Airbnb host will require more work in the form of turning over the room between stays. This is a super painless way to earn $500 to $1,000 a month without much effort – you may even be able to cover your mortgage payment with this extra income!

Business Income: Contrasting to the self-employed ones, the business owners do not do all the work on themselves. In fact they get things done by different set of people working for them and they run the business. They create a system which then functions smoothly even with minimal supervision. This calls for a much less risky position and allows you time to build more and more income sources for yourselves.
The industry reported a growth rate of around 10% from 1996–97 to 2000–01. After opening the sector, growth rates averaged 15.85% from 2001–02 to 2010–11.[citation needed] Specialised insurers Export Credit Guarantee Corporation and Agriculture Insurance Company (AIC) offer credit guarantee and crop insurance, respectively. AIC, which initially offered coverage under the National Agriculture Insurance Company (NAIS), has now started providing crop insurance on commercial line as well.[citation needed] It has introduced several innovative products such as weather insurance and insurance related to specific crops. The premium underwritten by the non-life insurers during 2010–11 was ₹42,576 crore (₹425 billion) against ₹34,620 crore (₹346 billion) in 2009–10. The growth was satisfactory,[according to whom?] particularly given across-the-broad cuts in the tariff rates. The private insurers underwrote premiums of ₹17,424 crore (₹174 billion) against ₹13,977 crore (₹140 billion) in 2009–10. Public sector insurers underwrote premiums of ₹25,151.8 crore (₹252 billion) in 2010–11 against ₹20,643.5 crore (₹206 billion) in 2009–10, a growth of 21.8% against 14.5% in 2009–10.[citation needed]
Agricultural and allied sectors accounted for about 52.1% of the total workforce in 2009–10. While agriculture employment has fallen over time in percentage of labour employed, services which includes construction and infrastructure have seen a steady growth accounting for 20.3% of employment in 2012–13.[351] Of the total workforce, 7% is in the organised sector, two-thirds of which are in the government-controlled public sector.[352] About 51.2% of the workforce in India is self-employed.[351] According to a 2005–06 survey, there is a gender gap in employment and salaries. In rural areas, both men and women are primarily self-employed, mostly in agriculture. In urban areas, salaried work was the largest source of employment for both men and women in 2006.[353]
The appeal of these passive income sources is that you can diversify across many small investments, rather than in a handful of large ones. When you invest directly in real estate, you have to commit a lot of capital to individual projects. When you invest in these crowdfunded investments, you can spread your money across many uncorrelated real estate ventures so individual investments don't cause significant issues.
Thirst for income is likely to continue with interest rates expected to stay low, keeping government bond yields low for longer and their valuations unattractive.  Looking past bonds, the prices of high-dividend shares are historically high, which limits the likelihood that their dividends will rise markedly from here.  Striving too high for an income target tends to push your portfolio further out on the risk spectrum.
