Nieche for life coaching business

Hi Brooke, I am refining my nieche for my life coaching business. I am using my own growth journey to model after. Affluent educated working women with kids who are looking to find their authentic self. Is it specific enough? Is authenticity something women will buy? They come to me looking for clarity, happiness ‘recipe’, tools to make decisions. Is authenticity the right word to describe what they are looking for? Thank you!
