Rachel Kirk explores self-worth—distinct from ego—as believing you belong, are capable, and are meant to do what you’re doing, noting that business growth often mirrors personal self-worth. She discusses how doubt is normal and often fueled by comparison, lack of experience, past failures, or being the newest, youngest, or a woman in a male-dominated industry, and reframes doubt as a sign of growth. She offers practical steps: act before you feel ready, stop seeking external validation, track wins, shift internal language from “who am I?” to “why not me?”, and put yourself in rooms where you can learn.
