Although adding income streams takes time, creating them within your current business is faster and easier than starting completely new income streams from scratch. This method of generating extra sources of income works well for any size business in any industry. For example, started by selling books. Today it sells thousands of other products including its own product, the Kindle, is a print and digital publisher, and now produces television shows. Many service-based business owners add coaching and books to their income streams.
Writing and publishing an eBook has become a widely popular means of earning passive income in recent years. eBooks on non-fiction topics like online marketing, business development, career advice, and the like are especially successful. While fiction eBooks are also good sellers, the market for them is much more competitive as compared to non-fiction ones. Once you've written an eBook, you can put it up for sale on platforms like Amazon's Kindle Direct Publishing or Apple's iTunes Connect.

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.
Developing passive income is different. With the exception of one of my passive income streams (cryptocurrency mining), all of the others require real, hard work. Truly, I understand the barriers for people getting into building alternative income streams. I would say that most people WANT passive income, but truly aren’t willing to put in the blood, sweat, and tears to make it happen.
I am an English major and a herbalist with so many ideas and no extra income to fulfill them. I recently started renting my extra apartment in the attic with Airbnb. It’s amazing how fast I accumulated some money for few hours of work between guests. Now I want to persue all my dreams of opening an online herbal store, publishing my ebook of treating Ulcerative Colitis with herbs, blogs, and videos, and pretty much all of the ideas mentioned here. I will save this article as its really helpful for whomever needs some ideas…
To your point about Municipal Bonds, my concern is tax reform. While everything is mostly being worked behind closed doors (and likely wont ever see the light of day). There is still the chance they propose to limit the amount of the tax free nature of these bonds. While I dont sen panic in the streets, I do see a scenario where bond prices get additional pressure because municipalities have to increase rates due to people putting their money to work elsewhere.
India's retail industry mostly consists of local mom-and-pop stores, owner-manned shops and street vendors. Retail supermarkets are expanding, with a market share of 4% in 2008.[247] In 2012, the government permitted 51% FDI in multi-brand retail and 100% FDI in single-brand retail. However, a lack of back-end warehouse infrastructure and state-level permits and red tape continue to limit growth of organised retail.[248] Compliance with over thirty regulations such as "signboard licences" and "anti-hoarding measures" must be made before a store can open for business. There are taxes for moving goods from state to state, and even within states.[247] According to The Wall Street Journal, the lack of infrastructure and efficient retail networks cause a third of India's agriculture produce to be lost from spoilage.[249]
For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
