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, Amazon.com 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.
If you have specialized knowledge in a certain topic, you can put together an online course to teach others. For example, if you have experience in real estate investing, you can create an online course “Real Estate Investing 101”. The benefit of an online course is that once you create the course material, you can sell it to as many people as you want.
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.
