According to Susan Witt's recent study, children generally come to their first conclusions about being male or female from their parents since typically they are the first people the child relates to and the nature of the relationship is intense. Besides parents giving children gender specific clothing, toys, and expectations, there are often many subtle messages about what is acceptable or not regarding gender. Witt's study showed that children that grow up with more androgynous gendered parents are more focused on achievements and typically have a better sense of self.  Conversely, in cases of gender nonconformity, when a child exhibits gender performances that are atypical of their prescribed gender role, Kerry Robinson reports that a parental figure may respond with hostility.  According to the Official Journal of American Academy of Pediatrics , people who do not conform to the gender binary are often subject to abuse from society, from within the family and within their community. Types of abuse range from physical and sexual to psychological abuse and are not associated with homosexuality alone. 
First, although the most obvious drawback of the emphasis on happiness involves the gaps with reality that can, paradoxically, create their own discontents, there’s also the risk that people will fail to explore reasons for dissatisfaction because of pressure to exhibit good cheer. We may miss opportunities to improve situations, for example in work settings, because we assume that problems result from personality and not from more-objective conditions. Those risks suggest the need to cut through the pervasive happiness rhetoric at certain points.
If I went to a doctor and said “Tell me how to diagnose a patient,” or I went to a judge and said “Tell me how to interpret the law,” or I went to an artist and said “Tell me how to be creative,” do you think they would be able give me a few sentences that completely answer my question and prepare me for professional work as a doctor, judge, or artist? If they had spent years as students learning their subject matter, and additional years teaching or writing a textbook on their specialty, they might be very good in their professions but I’d bet they’d all find it tough to answer such a question in any meaningful way.
