How do I Know if I Would be a Good Life Coach and Actually Enjoy It?

I signed up for coach certification and now I’m freaking out that I made a mistake. I’m not a phone person and find talking to people all day can be exhausting. I don’t even like to make recruiting calls and I’m a recruiter. How do I determine if being certified is the right thing? It’s a lot of money to spend, that I don’t really have. Using savings that should go to paying off credit card debt.
