Question about Niche

Hello! I’ve been operating a confidence coaching business very part-time for the past year and a half. I am ready to make coaching my full-time job and ready to fully invest in the business. My current niche is – I help women embody confidence and bravery in their health, relationships, and careers. But, I’m wondering if this is too broad? I tend to get women from all different ages and backgrounds, but I’m not sure if that’s a bad thing?
