B minus vs. careless

I started following my plan and opening up towards b minus work and getting it done. I have had two blunders so far, which are unlike me. My brain is instantly implying that I’m careless and should go back to my old ways of reviewing my work again and again. I still care about being rejected by anyone. I aim to reach a place of curiosity and kindness. After spinning in a loop for 2 hours and eating out of protocol, it doesn’t bother me much.
I still want to come from a place of compassion and believe that I won’t face harsh consequences for my upcoming blunders. I understand that my above thought is going to produce results. My question is
– How do I process transitioning from perfectionist to B minus with curiosity and compassion?
– Also, if I stop caring about getting external approval, should I delude myself in my world.
