Excellent collection of ideas!!! As always, very nice write up. Also for people interested in teaching say you are good in some technology, you can go and drop your CV to any training institutes which teach that technology. Most of the training institutes these days do not have full time faculty working for them, its mainly people working for some companies coming and taking part time classes as a visiting faculty either during weekdays/weekends. You just need to go teach and get your pay which will be either in terms of per hour basis or per course basis. Very effective way, though I do not do it now, I had used this for quite some time and made some good money.

​If you pay your bills with a credit card make sure it offers cash back rewards. You can let your rewards accrue for a while and possibly put the easy money you earned toward another passive income venture! (Be sure that the card you select doesn’t have an annual fee or you might be cancelling out your rewards). Check out this list of the best Cashback Rewards Cards.

4. Save, build and run a bread-n-breakfast place. Look at airbnb Vacation Rentals, Homes, Apartments & Rooms for Rent - Airbnb for inspiration. My wife runs one (Firdaus, Naukuchiatal) , it is not an income as of now but if you are on it for enough time, it would be, when you grow old. It doesn't have to be a fancy and glamorous thing. It could be a  2 nice-n-clean room in a city where you live. If you have a big house, it could be a  part of your house.

You can make money whichever way floats your boat. I got a lot of slack in this post for trading forex, but I live in one country, and need currency from three other countries where I own property and travel to often, so when one currency is cheap, I do take advantage of fluctuations. It may not be your thing, but the important part is that you have more than one source of income.
Finally, make sure you can service multiple types of clients. This is the best egg to have. Even for something as simple as a dog walking business, you can service multiple types of clients. For example, you can offer a puppy walking service and an adult walking service. You can have weekends at the park services. You can offer to take the dog to the groomers. Try to meet client’s individual needs.
India liberalised its FDI policy in 2005, allowing up to a 100% FDI stake in ventures. Industrial policy reforms have substantially reduced industrial licensing requirements, removed restrictions on expansion and facilitated easy access to foreign technology and investment. The upward growth curve of the real-estate sector owes some credit to a booming economy and liberalised FDI regime. In March 2005, the government amended the rules to allow 100% FDI in the construction sector, including built-up infrastructure and construction development projects comprising housing, commercial premises, hospitals, educational institutions, recreational facilities, and city- and regional-level infrastructure.[304] Between 2012 and 2014, India extended these reforms to defence, telecom, oil, retail, aviation, and other sectors.[305][306]
Mike, I don’t consider the income from FS to be passive, as I’m spending time commenting to you right now. But since 75% of my traffic comes from search, the most traffic I would probably lose is 25% for probably a year. And then my search word rankings would probably slowly fade given frequency of posting new content is one of the search algo variables.
Indoor air pollution resulting from the use of solid fuels [by poorer segments of society] is a major killer. It claims the lives of 1.5 million people each year, more than half of them below the age of five: that is 4000 deaths a day. To put this number in context, it exceeds total deaths from malaria and rivals the number of deaths from tuberculosis.Source 15
One of the most enjoyable ways to make more money is to turn your hobby into a paid side project – this way, you spend your spare time doing something you love whilst contributing towards your financial goals. There are plenty of different ways to convert your passion into cash, whether you turn it into a service or use it to make a sellable product. If your hobby is knitting, for example, you can sell your creations online through sites like Etsy or at local craft fairs. Equally, if you love animals, why not offer a local dog-walking service?
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.

Venture debt ($12,240 a year): The first venture-debt fund has returned almost all my initial capital, so I decided to invest $200,000 in the second fund. I took a risk investing $150,000 in my friend's first fund, so I'm hoping there's less risk in the second fund, given he has four more years of experience on top of his 12-plus years of experience running a venture-debt portfolio for another company.

It’s a (mostly) short term, higher risk, higher reward place to invest cash that has a low correlation with the stock market, but is far more passive than buying and managing properties, has more opportunity for diversification than private placements (minimums of 5-10K, rather than 100K), and most of the equity offerings (and all of the debt offerings) provide monthly or quarterly incomes. Unlike a REIT, you can choose exactly which projects you wish to invest in.
Investing in real estate: Investing in real estate offers more passive income cash potential - but more risk - than investing in stocks or bonds. You'll need substantial amounts of cash to invest in buying a home -- it usually takes 20% down to land a good home mortgage loan. But history shows that home prices usually rise over time, so buying home a for $200,000 and selling it for $250,000 over a five-year time period, for example, is a reasonable expectation when investing in real estate.
Hi Sam! I loved your sentence, “There’s so much information in my head that I need to write it down or else I might explode.” That’s exactly how I feel! I never thought of myself as a writer, and especially not a blogger, but recently I’ve started dabbling in it and it feels so nice to get everything out! I’m dedicated to helping others succeed with personal finances, and there are plenty of “how-to” sites, but it’s important to get people thinking and motivated to prepare, plan, and save!
As a private lender, you can lend to anyone in your social circle. For example, many home rehabbers need access to a source of capital they can tap into very quickly in order to fund the initial purchase of their properties. You can partner with a rehabber who uses your capital for a short-term in exchange for an interest rate that is mutually agreed upon.
I’ve never invested in real estate (except to live in), but am always intrigued by communities like FS who seem to have such a passion for it. My intrigue stems back to my earlier comments that the long term trends in appreciation in real estate are simply not very competitive versus equities, despite what Robert Kiyosaki had to say in his book, Rich Dad, Poor Dad.
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.
