What if I don’t want to have a specific Niche as a coach?

I remember a few weeks into my coaching program hearing how important it is to have a niche.. so you know who your ideal client is and can effectively market to them. I was bummed to hear that as I didn’t want to narrow myself down to a specific subject matter. 15 months later and I am still stuck on this. Nothing super specific resonates with me. Lots of things do !
My website is up, everything is in place, but I don’t have a specific niche and therefore don’t know how to get clients and now I’m feeling paralyzed .
