Just to be clear, being independent does not change the health status of an applicant. You statement shows that either 1) you assume it does or 2) you have the demeanor of a brat.
You are missing the point entirely. Everyone in the world has some type of health issue. A good agent will be able to analyze the health hx, and get the application approved. You need more experience, not better leads or being independent. Or maybe you can only write a guaranteed issue product. Or as my old John Hancock General Agent once said after an agent quit: "some people are just meant to work in a business where their name is written on their shirt"
