My Niche is a cute little monster

Hi! It’s taken me awhile to come up with my niche, but I finally sat down and applied some focus onto it. At first, it seemed daunting, but now that I’ve gotten it on paper, I see it as a cute little monster 🙂 hence the title! Anyways, I’m starting an online coaching business with this specific niche in mind:

25-29 year old female working registered nurses who have grown up with overly critical mothers and struggle with perfectionism, insecurity, and being “enough”. I help them to make peace with themselves by breaking their habit of self criticism so they can excel exponentially in their careers and personal lives, and become the best person they know.

I’d like to know if this is a specific enough niche or if there is any feedback that could help me. Thank you!!!
