Is this Niche narrow enough?

Young Widows (under 50) ready to build big, bold, beautiful new lives. These would be widows who have already done the initial hard work in therapy/bereavement counseling and have decided they want to be defined by more than their grief. My business is called Widows Like Us and I have 10 guiding principles for the kinds of women we will strive to be together. In the 7 years that I’ve been a young widow, I have chased my dreams and built a life I LOVE. I want to help other widows do the same by teaching them how to daydream, work backward from that dream, and take action TODAY that will bring them closer to building their “impossible” beautiful life.
