I can do whatever I want

I feel giddy and wild when I say this sentence. It almost makes me feel out of control, but also joyful. I think that the out of control part is the lizard brain telling me that of course I CANNOT do whatever I want. I have obligations, I need people please, no one will like you. but I just gently say to my lizard brain that if I like or love myself, I don’t really need anyone to like me. if I really and truly love myself I can do whatever I want.

Suggestions for how to try this out? how to really take this out on the road and fail at trying it?
