Decision Debt Podcast


Hi,
I re-listened to the decision debt podcast and I have a follow up question.
I chose a dress online (for a big family event) after a lot of research. I ended up not liking it after I tried it on. So I returned it.
In this case, I decided to buy a dress and re-decided to not keep it.
But if I chose a niche for my coaching business, try it out and decide it is not working. Should I decide to quit and try something else or coach myself to like/make it work?
Basically when do you know if you should coach yourself to stay with something vs deciding to moving away from it.
