Feeling legit to start my life coaching business

Hello dear Life Coach School team! I am starting my life coaching business and I am having a hard time believing that I am legit. The belief is that I won’t give my clients enough value, that I am not good enough, and not experienced enough yet.
I know we need to believe before seeing the evidence of it, but in this case it feels more difficult for me.
Any tips to walk that walk? Thank you for your support!
