A business thrives or fails depending on its marketing and system for generating leads. You need leads to make sales. No audience or exposure means you won’t get fresh faces checking out what your business does. Too many entrepreneurs spend all their time on the “busy work” and not enough on audience building. There are some great ways to build an audience and generate new leads:
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.
