Definition
Self-doubt is a lack of confidence in one's own abilities, qualities, or judgment. It involves questioning your decisions and feeling uncertain about your capabilities. Unlike healthy skepticism, self-doubt can be paralyzing and prevent you from taking action. It's that nagging voice in your head telling you that you're not good enough. Think of it as your inner critic constantly undermining your confidence. Self-doubt can stem from past failures, negative feedback, or unrealistic expectations.
