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]
When listing your collectibles online, selling through the right channels is key to ensuring you get the best price; look for specialist websites that are both specific to your niche and offer seller-friendly terms – luxury watch marketplace www.chrono24.com, for example, offers competitive listing fees starting at $5 US, a 90% sales rate and a money-back guarantee if your item doesn’t sell within six months. If you don’t already have a collection in place, it’s never too late to start – follow these tips on how to start a valuable collection.
Thanks for the great article…although I have to point out many of the items listed are not passive but active, such as selling bodily fluids, writing blogs or resumes, and collecting bottles and cans. To be truly passive, the income source must require no effort on your part (after initial setup). Real estate, dividends, P2P lending…these are truly passive income sources.
Obviously, these are much higher than you’re going to get with most other investments. What’s more is that you can choose a plan that matches your investment strategy, whether your goal is Supplemental Income, Balanced Investing, or Long-term Growth. You can also look at different real estate projects and choose for yourself which ones to invest in.

Building a website still remains a viable way of earning passive income online despite it being such a competitive venture. Since the internet is saturated with blogs, an entertaining website featuring quizzes or games is a good alternate. Such websites are not too difficult to make and they are easy to promote on social media. They can attract visitors, who will spend a significant amount of time on the site, in droves. Once a site starts recording several thousand visits each day, use the Google AdSense system to start earning revenue through advertising while you relax.

How do you do this?  Well, try to get the highest paying job you can!  Ask for a raise!  Utilize services, such as Glassdoor.com, to see how your salary competes with others in your same job.  Some companies really force employees to leave to get a raise, and then come back for another raise.   This industry jumping promotional strategy is very common and could work.
Multiple streams of Income covers this strategy. I highly recomend you read it if for that reason alone. Beats the typcial buy and hold (or is that buy and hope), dollar cost averaging and other so called sensible stategies which don't work unless you have a 20-30 year time horizon. Ask anyone who saw their investments plumet during the Jimmy Carter years back in the 70's how long they had to wait to get their investments back up to break even level. Want to take a guess? Would you believe 15 years? That is close.
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.
Most of us think of investment income as just the cash flow we get from bank interest, bonds, share dividends and property rents, some of which comes via a super pension.  But a more complete view is to also consider how growing the value of your investments can add to your spending potential.  This total return approach generates income from both income and growth to optimise spending from your portfolio across all market cycles, aligning cheap and expensive investments to your goals.
