Fake it until you make it. The body and mind are a bidirectional influence system. When you adopt an expansive and open "high-power pose" for just two minutes, it can significantly drop stress hormones and boost power and confidence hormones, thereby changing your subjective feelings and objective performance. For example, it can improve your performance in interviews or speeches. This change is not about tricking the brain; rather, it reshapes your sense of presence through physiological feedback, that is, believing in the power of your own body. Consciously utilizing it to shape your internal state is a powerful 'embodied cognition' tool that allows you to not wait to 'feel confident' before facing challenges, but instead to create confidence through action, that is, posture, thereby increasing the chances of success and ultimately achieving a positive cycle of 'becoming truly strong'.
