What are the benefits of building a book of business? That will generate your residual income. The first thing that comes to mind is income stability. One of the main reasons why agents quit this business is because of income instability. We all have had bad sales weeks and months. Which can be difficult to overcome if you don't have anything to fall back on. But having residual income coming in. Would not only help to make up for a bad week or month. But mentally put you in a better space. To continue in this business without the thoughts of quitting.
