Niche and Value proposition


I have a background in international business and personal development (coaching and meditative tools).

1- My Niche market is helping entrepreneurs to take care of their personal well-being while operating their business. I would like to go deeper into a micro Niche, but I do not know how I could go deeper.

2- In terms of value proposition I am having difficulties articulating it.

Could you help me with this please? Thank you very much
