Confusion regarding my next steps

Hello, I started my business coaching almost 2 years ago.

I have a 3-month program with individual coaching and training. I tend to work with different categories of people: People in corporate that relate to me and want to start their coaching practice; people that want to feel better; and people that want to work on their self confidence and self-esteem.

I feel like I want to go to the next level of my coaching business and I may need to choose a specific niche with a specific offer. But I feel confusion as soon as I start thinking about that. I want some help please to gain clarity around how to go from where I am (general life coaching) to where I want to be (more specific and maybe scalable business).
