How passive it really is: Excellent – Once your ads are running, you could literally just sit back and watch the money roll in.  Again, you are spending money to make money here, so there is risk involved.  However, once the ads are set, the income can be very passive.  Keep in mind, you may need to monitor and possibly modify ads if they aren’t performing well.

If you happen to be a photography enthusiast, consider selling your photos to stock-image websites like Shutterstock, Alamy, and iStockPhoto.

The income generated from sale of goods or services, or any other use of capital or assets, associated with the main operations of an organization before any costs or expenses are deducted. Revenue is shown usually as the top item in an income (profit and loss) statement from which all charges, costs, and expenses are subtracted to arrive at net income. Also called sales, or (in the UK) turnover.
An employee's main job location (principal place of work) is usually the place where the employee spends most of his or her working time. If there is no one place where most of the work time is spent, the main job location is the place where the work is centered, such as where the employee reports for work or is otherwise required to base his or her work.

The five-year plans, especially in the pre-liberalisation era, attempted to reduce regional disparities by encouraging industrial development in the interior regions and distributing industries across states. The results have been discouraging as these measures increased inefficiency and hampered effective industrial growth.[397] The more advanced states have been better placed to benefit from liberalisation, with well-developed infrastructure and an educated and skilled workforce, which attract the manufacturing and service sectors. Governments of less-advanced states have tried to reduce disparities by offering tax holidays and cheap land, and focused on sectors like tourism which can develop faster than other sectors.[398][399] India's income Gini coefficient is 33.9, according to the United Nations Development Program (UNDP), indicating overall income distribution to be more uniform than East Asia, Latin America and Africa.[10]

With websites like Ebay and OLX, you can now sell virtually anything on internet to those who are looking for products. So you can do some handicraft or anything else, which can be created at home in extra time and then it can be sold on ebay. Or you can find some local product which others would find awesome, but its not available in other parts of country and then start selling it online for a profit. Even you can look at some products which are selling at huge discount at stores (wholesale market or under clearance sale) and then sell it on amazon at regular price.
OK, I know what you're thinking — maybe you're not a writer. However, as Tamez says above, chances are, you're an expert sy ~something~. Also, chances are that other people want to know what you know. So whether you write an eBook on dating or tips on how to fix your car, once you write, self-publish the book, and let it go, it can sit on a site like Amazon and sell itself. Of course, you can market it, too, but that's another story! Some sites let you keep most of the earnings, while others do not.
What I’m doing: I use this site to write out goals like 1) Generating $200,000 a year working 4 hours a day or less, 2) Trying to make winning investments, and 3) Keeping track of my passive income streams with free financial tools. My site and the community helps keep me accountable for progress. It’s important I do what I say, otherwise, what the hell is the point? You should consider starting a site or at least a private journal. Write out your specific goals, tell several close friends and stick to the plan.

The one thing I learned though from all those childhood experiences though is that you never can depend on one source of income. Eventually my mom caught on and stopped giving me all those extra bags of chips and I had to figure out a new way to make money. No matter how safe something seems there’s always the chance that you could lose that income and be stuck with nothing.

Although renting out your room or home can also be a side hustle to make extra cash, it's also a great source of passive income. However, another route to go is to get an income property just for the purpose of renting it out. This is even better if you live in a touristy area, because you can probably make even more than usual during the high tourist seasons.
So one thing I have to disagree with after having done hours and hours of research from Multiple CPA’s is “Dividends – 21% (passive)”. Thats actually not right. Thats actually “active”. I actually paid 2 different CPA’s to do research on this topic. One of them I paid 500 dollars to actually dig out the IRS tax code and “prove” it. If you are active in a business and the business pays you dividends its still active income (not passive).
As the third-largest economy in the world in PPP terms, India has attracted foreign direct investment (FDI).[301] During the year 2011, FDI inflow into India stood at $36.5 billion, 51.1% higher than the 2010 figure of $24.15 billion. India has strengths in telecommunication, information technology and other significant areas such as auto components, chemicals, apparels, pharmaceuticals, and jewellery. Despite a surge in foreign investments, rigid FDI policies[302] were a significant hindrance. Over time, India has adopted a number of FDI reforms.[301] India has a large pool of skilled managerial and technical expertise. The size of the middle-class population stands at 300 million and represents a growing consumer market.[303]

At age 55, I own high-end rental properties (near the beach) and commercial buildings servicing the medical industry. I was widely criticized during my career for not living up to my income; that is, buying big homes with many fancy cars. I married a great woman who understood that saving and investing today meant a better lifestyle and more freedom tomorrow. Our passive income is half of my active income from sales, but my net worth has increased substantially. We are both happier and healthier than we were in the high-stress pressure cooker of franchise sales. The naysayers have become converts to the concept of passive income, but they have locked themselves into a “big hat, no cattle” lifestyle. It has been a great ride!
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.
