Do you want to earn $100, $1000 — or even more — on the side? You can start earning extra income today with the help of this list of ideas I’ve put together. Spend an hour or two each day working on items that are practical for you, and you can build alternative income sources to help you improve your financial situation  While many of the items on this list are passive income ideas, not all of them are. Some items require you to actively work for success.
In 2012, even I wrote a 150-page eBook about severance package negotiations that still regularly sells about ~35 copies a month at $85 each (2nd edition for 2017) without any effort. In order to generate $2,975 a month or $35,700 a year in passive income as I do now, I would need to invest $892,500 in something that generates a 4% yield! To earn $10,000 a year in passive income would therefore need roughly $250,000 in capital.

P.S. I also fail to understand your fascination with real estate. Granted we’ve had some impressive spikes along the way, especially with once in a life time bubble we just went through. But over the long term (see Case Shiller real estate chart for last 100 years ) real estate tends to just track inflation. Why would you sacrifice stock market returns for a vehicle that historically hasn’t shown a real return?

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.

Finally, I imagine the biggest debate with my ranking is Creating Your Own Product as the #1 passive income source. If most people have never created their own product, then it’s easy to give it a thumbs down. There won’t be much complaint about Private Equity Investing being in last place because most people are not accredited investors. But given I believe that plenty of people can create their own product if they try, pushback is inevitable because a lot of people simply don’t try!
For the 95% on $10 a day, see Martin Ravallion, Shaohua Chen and Prem Sangraula, Dollar a day revisited, World Bank, May 2008. They note that 95% of developing country population lived on less than $10 a day. Using 2005 population numbers, this is equivalent to just under 79.7% of world population, and does not include populations living on less than $10 a day from industrialized nations.
It is hard to do both but you’re not supposed to. You’re supposed to get your safety net down THEN try to do high wire acrobatics above it – not set up the two at the same time. So get retirement and your emergency fund squared away, then consider the stock market (taxable) and real estate. There’s no rush! Don’t let others dictate your future because they don’t have the same priorities as you. 🙂
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.

Industry accounts for 26% of GDP and employs 22% of the total workforce.[165] According to the World Bank, India's industrial manufacturing GDP output in 2015 was 6th largest in the world on current US dollar basis ($559 billion),[166] and 9th largest on inflation-adjusted constant 2005 US dollar basis ($197.1 billion).[167] The industrial sector underwent significant changes due to the 1991 economic reforms, which removed import restrictions, brought in foreign competition, led to the privatisation of certain government-owned public-sector industries, liberalised the foreign direct investment (FDI) regime,[168] improved infrastructure and led to an expansion in the production of fast-moving consumer goods.[169] Post-liberalisation, the Indian private sector was faced with increasing domestic and foreign competition, including the threat of cheaper Chinese imports. It has since handled the change by squeezing costs, revamping management, and relying on cheap labour and new technology. However, this has also reduced employment generation, even among smaller manufacturers who previously relied on labour-intensive processes.[170]

However, under certain circumstances, payment for personal services performed in the United States is not considered income from sources within the United States. For example, personal services performed by an independent nonresident alien contractor specifically exempted by a tax treaty. For more examples, see the Pay for Personal Service section in Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities.
The services sector has the largest share of India's GDP, accounting for 57% in 2012, up from 15% in 1950.[165] It is the seventh-largest services sector by nominal GDP, and third largest when purchasing power is taken into account. The services sector provides employment to 27% of the work force. Information technology and business process outsourcing are among the fastest-growing sectors, having a cumulative growth rate of revenue 33.6% between fiscal years 1997–98 and 2002–03, and contributing to 25% of the country's total exports in 2007–08.[194][needs update]
For example my business is a LLC taxed as a S corp. I am active in it and my wife is not. She owns half the company because she fronted the money to start the company (but is not active at all in the business). I get paid a W2 salary for my work I put into it and any profits are distributed to my Wife and I as “dividends”. However the dividends are still taxed as active income at the higher tax rates.
What's crazy is that my book income is more than my SF condo-rental income. Yet I didn't have to come up with $1.2 million of capital (the minimum cost to buy my condo today) to create my book. All I needed to create my book was energy, effort, and creativity. I truly believe that developing your own online product is one of the best ways to make money.
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
