You’ve heard both sides: Overconfidence makes you feel good, gives you grit, and impresses others—but can also make you an arrogant jerk who alienates people, doesn’t improve, and possibly loses everything because of denial. Being less confident gives you the drive and tools to become an expert and makes other people like you . . . but it doesn’t feel so good and can send a lousy signal to others about your competence. Kinda sucks, doesn’t it? Seems like there’s no easy answer. You can impress people and make them angry or have them like you but not respect you. It feels like a contradiction.
