You know the voice. The one that says you're not good enough. That you're going to mess it up. That everyone else has it figured out—except you. For high performers—executives, athletes, veterans, and ambitious professionals—this internal critic can be relentless. It might sound like motivation, like it's pushing you to do more or be better. But underneath it, there's often fear: fear of failure, rejection, being seen, or not being enough.
