Weird Niche

Narrowing down my niche – and I had a weird idea. I’ve spent the past 20+ years in the network marketing industry. Many of these companies have weight loss products (pills, shakes, plans, etc.) I was thinking about offering weight loss coaching to women involved in network marketing opportunities. Is that a weird niche? I could even go tighter and target women in a specific company (Weight Loss for Women in Herbalife) … but maybe that would work more for FB ads. Maybe I’m overthinking (or mis-thinking) niching.
