I feel like I don’t know what I am good at as a life coach so I know how to make an irresistable offer

I’ve been doing life coaching for 4 years now, part-time. I am committed to making it full time now, my maternity leave is almost over. I am looking over getting more specific for my niche and wonder what I am good at. Any tips on how to figure this out so I can know how to narrow down my niche? I love working with women/leaders so they can get over what is blocking them from accessing their next level. I know it’s not clear enough.
