Anxiety can make one step feel as if it must be perfect before it is allowed to happen. The voice is loud, the body reacts, and the next action seems to carry an impossible amount of meaning. An action anchor cannot erase that experience. It can stop the final round of inner argument from deciding your life for you.
Ready or not, here I go is not reckless self-command. It is for the moment after you have prepared, checked what is real, and recognised that further doubt is not adding useful information. It brings attention from imagined catastrophe back to the next physical movement.

Built from the Project Anxiety transcript extraction, lines 90–97. The phrase is presented as a prepared action anchor, not a cure, safety instruction, or substitute for support in severe distress.
