Niche idea? (epm)

I’ve been playing around with several niche ideas while waiting for coach training next year… I’ve been thinking weight loss since I was thinking that would be the ‘most popular,’ and is part of my experience but, truthfully, I haven’t been feeling that in my gut, so today I thought, ‘Okay, really, who AM I?’ and I realized I am ALREADY someone who, for years, has mentored women married to alcoholics and I have LOVED that work and have been so fulfilled and energized by it. So, what if my niche is women whose husbands have been sober for at least two years who struggle with their marriage but who want to STAY married? It works on the niche form and I know there are women out there for whom Al-anon does not resonate, but coaching absolutely might!! Thoughts?

Thank you!!!!!
