Niche clarity

I am a life coach. My niche is spiritual women who want to learn about manifestation to create the life of their dreams. Is this specific enough? About 60 percent of my clients have their own business, so I could niche further to entrepreneurial spiritual women. But some of my courses are designed not just for business, but for creating life goals. I guess I am asking if manifestation/metaphysics is niche enough, or go deeper?
