“And in situations where a man and a woman each receive negative feedback, the woman's self-confidence and self-esteem drop to a much greater degree. The internalization of failure and the insecurity it breeds hurt future performance, so this pattern has serious long-term consequences.”

“Being confident and believing in your own self-worth is necessary to achieving your potential.”

“Success and likeability are positively correlated for men and negatively for women. When a man is successful, he is liked by both men and women. When a woman is successful, people of both genders like her less.”

“As an associate at McKinsey & Company, my first assignment was on a team that consisted of a male senior engagement manager (SEM) and two other male associates, Abe Wu and Derek Holley. When the SEM wanted to talk to Abe or Derek, he would walk over to their desks. When he wanted to talk to me, he would sit at his desk and shout, "Sandberg, get over here!" with the tone one might use to call a child or, even worse, a dog. It made me cringe every time. I never said anything, but one day Abe and Derek started calling each other "Sandberg" in that same loud voice. The self-absorbed SEM never seemed to notice. They kept it up. When having too many Sandbergs got confusing, they decided we needed to differentiate. Abe started calling himself "Asian Sandberg," Derek dubbed himself "good-looking Sandberg," and I became "Sandberg Sandberg." My colleagues turned an awful situation into one where I felt protected. They stood up for me and made me laugh. They were the best mentors I could have had.”
