Diamonds are a Girls Best Friend

I'm watching the movie Marilyn, about Marilyn Monroe. I, like many others, have always been intrigued by her. I knew about her drug and alcohol abuse, marriages and affairs, but not so much about her insecurities. They obviously ran very deep and she needed constant reassurances that she was good enough in all areas of her  personal and especially business life. In 'regular' life it's difficult enough to feel unworthy of your life. Who wants all of their insecurities and failures broadcast around the world? We only want others to see only the best of who we are.  It would have known much more about Norma Jean.
