Most founders and executives I work with are uncomfortable talking about how they look. It feels shallow. Not the point. I get it. They started their companies because of a vision, not an ego. By the time they're working with an advisor, they're wrestling with real problems: who belongs in which seats, how to build accountability, how to run a leadership meeting. Thinking about personal image can feel self-indulgent by comparison.
