For throughout history, you can read the stories of women who – against all the odds – got being a woman right, but ended up being compromised, unhappy, hobbled or ruined, because all around them, society was still wrong. Show a girl a pioneering hero – Sylvia Plath, Dorothy Parker, Frida Kahlo, Cleopatra, Boudicca, Joan of Arc – and you also, more often than not, show a girl a woman who was eventually crushed.
