Narrowing Your Niche Question

When it comes to the Narrowing Your Niche Worksheet, I feel stuck. Here is why: My business is similar to Brooke’s in that I have a special coaching system that I can use for all life struggles. So, when I do my weight loss funnel or my relationship funnel, it will be simple to create the niche. BUT when it comes to the overall BRAND and my first main funnel for my life coaching school, how do I narrow that down? Do you know what I mean? Brooke has the model and I have my personality destiny system (astrology). I do not want to brand it as astrology though. Any advice if your result is a “total life solution”?
