In all the books I've read being introvert, being shy is okay, because in the end they are special, they have a happy ending. In reality, the world will tear you apart and wear you down. Being shy is never acceptable specially if you didn't come from a well off family. how can you feed yourself and your loved ones if you keep on being shy. Your not even that smart, that lucky or that talented, you don't have the characteristics for it to be okay being shy and introverted.
