Belief in Coaching; My Coaching Business

I want to leave my current job and transition to become a full-time coach.

I did comprehensive training (not LCS) but have not been consistently coaching since my training.
I made 5K last year coaching and offering Mindfulness workshops.

I think the issue is that I struggle to believe that coaching is “that” valuable, so I have a hard time charging as much as I want and need to leave my current job for it.

Although I have received a great deal of awareness from coaching, I haven’t really gotten the results I want, and it’s been over 2 years since I completed my coaching training, so I’ve lost my faith in it, or maybe I’m scared that I’m not good at it?

I’m feeling stuck.
