Bestselling author Rachel Simmons argues that in lionising the Good Girl we are teaching girls to embrace a version of selfhood that sharply curtails their power and potential. Unerringly nice, polite, modest, and selfless, the Good Girl is a paradigm so narrowly defined that it's unachievable. When girls inevitably fail to live up-experiencing conflicts with peers, making mistakes in the classroom or on the playing field-they are paralysed by self-criticism, stunting the growth of vital skills and habits. Simmons traces the poisonous impact of Good Girl pressure on development and provides a strategy to reverse the tide. .
