With everything in life from getting jobs and forming relationships requiring some degree of networking, introversion makes this practically a non starter. Call this a “hate the game not the player” type of issue if you’d like, but people should do everything it takes to get out of being an introvert, whether it be practicing public speaking or taking several shots of vodka and go talk to people. Maybe its a tactic of trying to get people to feel better about themselves, but I have no idea why introversion is considered to be equal to extroversion.
