Further north, the Saurashtra and Bengal coasts played an important role in maritime trade, and the Gangetic plains and the Indus valley housed several centres of river-borne commerce. Most overland trade was carried out via the Khyber Pass connecting the Punjab region with Afghanistan and onward to the Middle East and Central Asia.[69] Although many kingdoms and rulers issued coins, barter was prevalent. Villages paid a portion of their agricultural produce as revenue to the rulers, while their craftsmen received a part of the crops at harvest time for their services.[70]
Hannah UnplannedFinance That’s a good way of putting it, Hannah. I would say it’s better to get into the investing game before an emergency comes up, of course, so that your investment income is a bit more stable (hopefully). They’re good parts to include in your whole plan, which should be a balanced one. I was coming at this from more of a “how to prepare” perspective.

Sam…just read this article and I want to say that this is the best posting on passive income I have ever read…in a blog, article, or book. Thanks for making a difference and being an inspiration as to how it can all be accomplished. One of the great benefits of the internet is that people are willing to share their stories and experiences with each other online. If we had this when I was working professionally (20-40 years ago), it would have saved me from making some rather poor financial decisions that affected my retirement income. In a way, the internet is making up for the loss of financial security in the loss of The Defined Benefit Plan for retirement. Bravo!
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.

You've probably read blog posts and articles that recommend a certain brand of backpack or water, so you click on their hyperlinked link. Oftentimes, that person gets paid a commission when you do. If you have a blog, the same can happen for you. It's a win-win-win for everyone involved — you, the product you're recommending, and the person who clicks on the link to get the product. Pat Flynn talks about this at length on his website, Smart Passive Income, where you can learn a whole lot more on the topic, aside from affiliate marketing.

If you are good at some subject, especially maths, science subjects, accounts or economics, you will have an upper hand in this business. There are plenty of such coaching centers so you will have to face some stiff competition in the beginning. But if you can get good results from your students, congratulations! You have made yourself a name and now parents will send their children in big groups to your center.

You must sacrifice the pleasures of today for the freedom you will earn tomorrow. In my 20s, I shared a studio with my best friend from high school and drove beater cars worth less than 10% of my annual gross income. I'd stay until after 7:30 p.m. at work in order to eat the free cafeteria food. International vacations were replaced with staycations since work already sent me overseas two to four times a year. Clothes were bought at thrift shops, of course.
Having discussed why it is important to have a second source of Income, let me now highlight some of the sources of a second income or second income ideas. A second source of Income typically means having regular income from a source other than your primary one. This means, if you belong to a salaried class, you might want an income from some other source and if you are from a business class, you might want an income from some other business. You can be as creative as it gets. Some good sources of Income are highlighted below:
India has made progress increasing the primary education attendance rate and expanding literacy to approximately three-fourths of the population.[389] India's literacy rate had grown from 52.2% in 1991 to 74.04% in 2011. The right to education at elementary level has been made one of the fundamental rights under the eighty-sixth Amendment of 2002, and legislation has been enacted to further the objective of providing free education to all children.[390] However, the literacy rate of 74% is lower than the worldwide average and the country suffers from a high drop-out rate.[391] Literacy rates and educational opportunities vary by region, gender, urban and rural areas, and among different social groups.[392][393]
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.
