Why does this matter? Boy, it matters a lot. Because no one gets to the corner office by sitting on the side, not at the table, and no one gets the promotion if they don't think they deserve their success, or they don't even understand their own success.I wish the answer were easy. I wish I could go tell all the young women I work for, these fabulous women,"Believe in yourself and negotiate for yourself. Own your own success." I wish I could tell that to my daughter. But it's not that simple. Because what the data shows, above all else, is one thing, which is that success and likeability are positively correlated for men and negatively correlated for women. And everyone's nodding, because we all know this to be true.There's a really good study that shows this really well. There's a famous Harvard Business School studyon a woman named Heidi Roizen. And she's an operator in a company in Silicon Valley, and she uses her contacts to become a very successful venture capitalist.
