No one should turn down wind farming’s ultimate passive income for the next 30 or more years … even 60 years when there is a positive cash flow on the sum total of all base payments when computing inflation for the next 60 years based on the previous 60 years, as long as the next era’s energy resource is not perfected (at which time they would not renew the option for the second 30 years).
However, you should pick a niche and blog about that. If you're launching a money related blog, maybe it'll be about how to make money in real estate or simply how to make money online. Pick the niche and stick to it. If it's a diet and fitness related blog, maybe the niche is the Ketogenic diet, the Atkins diet or some other form of diet or fitness.
I would throw in some caution here: if your spouse works at the same company, or in the same industry as you, you are not diversified, and should something happen, you could be in a world of hurt.  Companies do go out of business, companies do lay employees off.  There is nothing wrong with working together, but realize that you are not diversified and you should be trying to maximize other income streams as a result.

And, let’s face it; not everyone wants to sling body wraps or nutrition shakes to their family and friends. That’s why offering a service is often one of the best, and least uncomfortable, ways to earn side income doing something you love. Maybe you want to clean houses or rake leaves or help people file their taxes. It’s totally up to you, and that’s the beauty of this option.
Pardon for being a bit of a newbie to true investing outside of a 401k. What about those of us who have 1) Just been laid off, and unable to find work due to lack of a degree (apparently 17 years in the industry with 5 certifications is just simply not enough – which is okay. It gave me the kick in the arse to get back to school finally) 2)Have three children to support (age 11 and under), and 3) Oh yeah – cannot find work. What do you recommend when the only source of positive revenue has ceased to come in and you now have less time than ever – due to responsibilities (i.e. doing well in university = academic scholarships means investment in time, plus spending 20 min breaks with kiddos) – to create positive sources of income ? I truly am wondering from an investor’s point of view how you would handle the pivot point of life if ever you had been faced with it. I realize this may be only imaginary, but at this point, I welcome your “what ifs” scenario on this one. You’ve truly done amazing work and I thank you for being so transparent.
First of all, let's face the facts. Working 9 to 6, you won't have any time during the day. If you choose to have a second job during the evening hours, you'd get burnt out very easily. Chances are that you might under-perform in both the jobs. I recommend having a side business rather than a second job. Some investment of money and time would be required at first. I have come up with a few options that would require less work from you but would be a decent second source of income.
No one wants to plan for a loss but it is always better to be prepared. US have recently seen a real estate meltdown that has caused the entire economies of the world to go into recession. So, it is very important to foresee such meltdowns and be prepared for losses. A second income source will ensure that you have enough rotational money to see you through losses.
“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.

India is the largest producer of milk, jute and pulses, and has the world's second-largest cattle population with 170 million animals in 2011.[161] It is the second-largest producer of rice, wheat, sugarcane, cotton and groundnuts, as well as the second-largest fruit and vegetable producer, accounting for 10.9% and 8.6% of the world fruit and vegetable production, respectively. India is also the second-largest producer and the largest consumer of silk, producing 77,000 tons in 2005.[162] India is the largest exporter of cashew kernels and cashew nut shell liquid (CNSL). Foreign exchange earned by the country through the export of cashew kernels during 2011–12 reached ₹4,390 crore (₹ 43.9 billion) based on statistics from the Cashew Export Promotion Council of India (CEPCI). 131,000 tonnes of kernels were exported during 2011–12.[163] There are about 600 cashew processing units in Kollam, Kerala.[160] India's foodgrain production remained stagnant at approximately 252 million tonnes (MT) during both the 2015–16 and 2014–15 crop years (July–June).[164] India exports several agriculture products, such as Basmati rice, wheat, cereals, spices, fresh fruits, dry fruits, buffalo beef meat, cotton, tea, coffee and other cash crops particularly to the Middle East, Southeast and East Asian countries. About 10 percent of its export earnings come from this trade.[17]
Scholarships, fellowships, and grants are sourced according to the residence of the payer. Those made by entities created or domiciled in the United States are generally treated as income from sources within the United States. However, refer to Activities Outside the United States, below. Those made by entities created or domiciled in a foreign country are treated as income from foreign sources.
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.
Perhaps a coworker purposefully tries to make your life miserable because they resent your success. Maybe you get passed over for a promotion and a raise because you weren’t vocal enough about your abilities, and mistakenly thought you worked in a meritocracy. Or maybe you have a new boss who decides to clean house and hire her own people. Whatever the case may be, you will eventually tire.

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]
If social capital is expecting to benefit from a share of the human capital of others, there may not be enough “others” in future generations to contribute to the well being of the current generation. It is interesting to speculate about how much guaranteed income the economy can be expected to support at any given time and for what categories of people.
