Duplicate niche


I know that oftentimes we end up working with women like ourselves because then we completely identify with their struggles. I want to work with women like me, however the problem is there is already a life coach from the life coach school who is already working in that exact same niche who is already extremely successful and who I respect very very much. I have some concerns! 1. I don’t want to compete with her and 2. I feel like since she’s already established who would people want to work with me? I’ve thought about coming up with a slightly different niche, but keep coming back to what I’m really passionate about, my people, my niche. Any thoughts about proceeding forward?
