This can be a little easier said than done, but if you have a large social media following, you can definitely earn money promoting a product or advertising for a company. You can even combine this with different marketing campaigns if you are an influencer and have your own blog (advertisement + affiliate income). This is how many bloggers make money! Again, it is not 100% passive but once set up correctly and then scaled, can be surprisingly lucrative.
Lots of good insights here. I’ve just recently gotten my own website for making online income. Also gotten a website for my fledgling voice over business. There’s a lot to learn when it comes to making passive income online, especially if you’re not financially savy, this is a very helpful blog in that regard, with all the useful tools and reference materials, it certainly removes a lot of guesswork.
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).
Quick story: Remember that $1.18 I found in the couch? Even when that increased to $30 to $50 a day, it still wasn’t enough to live on. So I looked for other options. In August 2008, after people started to know who I was and how I could help them pass the LEED certification exam through my blog, I wrote an ebook. It included all the information I knew about passing this exam, and I sold it on my blog for $19.95.

Historically, India has classified and tracked its economy and GDP in three sectors: agriculture, industry and services.

Industry includes various manufacturing sub-sectors. India's definition of services sector includes its construction, retail, software, IT, communications, hospitality, infrastructure operations, education, healthcare, banking and insurance, and many other economic activities.[150][151]
As interest rates have been going down over the past 30 years, bond prices have continued to go up. With the 10-year yield (risk free rate) at roughly 2.55%, and the Fed Funds rate at 1.5% (two more 0.25% hikes are expected in 2018), it’s hard to see interest rates declining much further. That said, long term interest rates can stay low for a long time. Just look at Japanese interest rates, which are negative (inflation is higher than nominal interest rate).
An obvious example is over exposure to bank stocks, which have been excellent investments for over a century.  Though a foundation of most portfolios, bank stocks do involve more risk at certain stages of the economic cycle than many realise.  Being less exposed to bank shares in the last few months could have preserved some capital.  So, a more diversified approach can help mitigate some of these risks.
