A Nice Guy, according to Dr. Robert Glover, a pioneering expert on the Nice Guy Syndrome, is a man who believes he is not okay just as he is. He is convinced that he must become what he thinks others want him to be liked, loved, and get his needs met. He also believes that he must hide anything about himself that might trigger a negative response in others.The Nice Guy Syndrome typically begins in infancy and childhood when a young boy inaccurately internalizes emotional messages about himself and the world. It is fueled by toxic shame and anxiety. Rapid social change in the late 20th century and early 21st century has contributed to a worldwide explosion of men struggling to find happiness, love, and purpose.
