Small niche when starting my business?

Hi coach.

I am starting my coaching business. I have been coaching for over a year (not as consistent as I would like due to lack of clients) and now I have figure out my WHO.

My question is: Is it okey if I have a really niche down niche when I am just starting? Would it be helpful for my business to do such a move in my marketing. Meaning instead of coaching relationships in general, I will be coaching women who want to forgive their partners and love again.

Not sure if in a starting business it is okey to narrow it down that much. Thanks for the input! 🙂
