Coachin niche


I am trying to figure out a coaching niche. I love working with young adult women. I have a lot of great techniques for stress and anxiety and was thinking of making that my niche. A part of me is concerned that i dont have at least a masters in sychology altbough the people i have helped say I was more effective than any therapist they have tried. I prefer meeting in person at my office or walk and talks. Does that make my focus too narrow? This age group is also looking for help with career and rekationship help too. Or do i have anxiety as my focus fir all age groups. I am also passionate about helping people who are lonely. Thought about that as a niche or maybe adding that to anxiety, but dont think too many peole will be searching for that. Your thoughts?
