Earning sources include books, courses, merchandise, coaching, freelancing, speaking, training, selling advertising, and affiliate marketing. For example, a virtual assistant can create tangible or digital products, such as books, courses, and videos that teach others how to be a virtual assistant in the “products” spoke. For services, she can offer additional services, coaching or speaking (i.e., How a Virtual Assistant Can Save Businesses Time and Money). Under other, she can expand her business by bringing on contract virtual assistants and become a manager of a VA company. Not all businesses will be able to come up with ideas for each spoke, but every business should be able to develop extra income streams from their home business idea.
“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.

If you happen to have a blog that attracts a large, devoted viewer base each day, then selling branded products on it is an excellent way to make a little extra money. Things like t-shirts, posters, mugs, and bags that feature your brand name, or some witty copy that your niche may find attractive, will definitely find buyers on your site. You can also link up with affiliate marketers to drive more sales if the business seems to be working out.

Ebooks are one of my favorite sources of passive income. Now, you can do this the simple way and just publish it on Amazon's KDP. Or, you can go all out and build yourself a book funnel. Book funnels are powerful, but they won't be fully passive. For example, if you do a free-plus-shipping offer for your ebook (converting it into a physical book), you'll need to create some one-time offers (i.e. extra training) and up-sells (i.e. an audiobook). But, a book funnel can be very powerful.

Nearly 50% of India's mining industry, by output value, is concentrated in eight states: Odisha, Rajasthan, Chhattisgarh, Andhra Pradesh, Telangana, Jharkhand, Madhya Pradesh and Karnataka. Another 25% of the output by value comes from offshore oil and gas resources.[270] India operated about 3,000 mines in 2010, half of which were coal, limestone and iron ore.[271] On output-value basis, India was one of the five largest producers of mica, chromite, coal, lignite, iron ore, bauxite, barite, zinc and manganese; while being one of the ten largest global producers of many other minerals.[268][270] India was the fourth-largest producer of steel in 2013,[272] and the seventh-largest producer of aluminium.[273]
After employment, I think that most individuals gain income diversification through investing.  It is important to look at why we invest: because at some point we plan on using this money for something.  For most, it is saving for retirement, and the investing is done through vehicles, such as a 401(k) or IRA.  But investing is not just about stashing money away for a rainy day – that is what an emergency fund is for.  Investing is about having enough capital to generate income.
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.
7) Never Withdraw From Your Financial Nut. The biggest downfall I see from people looking to build passive income is that they withdraw from their financial nut too soon. There’s somehow always an emergency which eats away at the positive effects of compounding returns. Make sure your money is invested and not just sitting in your savings account. The harder to access your money, the better. Make it your mission to always contribute X amount every month and consistently increase the savings amount by a percentage or several until it hurts. Pause for a month or two and then keep going. You’ll be amazed how much you can save. You just won’t know because you’ve likely never tested savings limits to the max.
Active income is needed because you know you can always push away to bring in steady income. Passive income is needed to bring in a little extra on the side. You must ensure to never put all your eggs in one basket. When generating multiple streams of income, you must have different sources to rely on – because in the end, nothing is 100% reliable.
What’s also really important to realize here is that when I took the exam I was teaching people to study for, I didn’t get a perfect score. In fact, I didn’t even get close to a perfect score. I passed. But I also knew a lot about this exam—way more than somebody who was just getting started diving into studying for it. And it was because of that, because I was just a few steps ahead of them, that they trusted me to help them with that information. To support this, I provided a lot of great free value to help them along the way. I engaged in conversations and interacted in comments sections and on forums. Most of all, I just really cared about those people, because I struggled big-time with that exam myself.
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
