Changing from Engineer to Family Health Coach

I want to work towards becoming a Family Health Coach. I’d be quitting my engineer career of 10 years. I’ve done model work for about 8 months. I just don’t think engineering is a good fit anymore. I feel total peace that this career journey is complete. I am worried that changing my circumstance is anti- model work. That I should feel good staying in my engineer job instead of looking for change. I do feel the change would result in a more fulfilled higher paying field for me. When is it ok to change the circumstance line?
