I am working on my Niche – Personal Mastery

I am a life coach and I feel I want to offer a service that helps people turn up as the best version of themselves. To be their most authentic self. Free from emotional baggage that are holding them back. Free from self-sabotaging behavior.
However I am not sure if this falls into the health or relationship area of narrow your niche questionnaire. Can self-mastery be about helping the individual become the best version of themselves? Or do I need to change my market?
can it be: Reinvent Your Life – Improve your relationship with yourself by becoming the best version of who you are and start turning up as a whole and complete individual. ?
