Reshma Saujani, founder of Girls Who Code, is on a mission to get more young women into computer science. She says the problem isn't lack of interest. Her non-profit organization has trained thousands of girls to code, and the ranks of female science and engineering graduates continue to grow. And yet men still dominate the tech industry. Saujani believes companies can certainly do more to promote diversity. But she also wants girls and women to stop letting perfectionism hold them back from volunteering for the most challenging tasks and jobs. She is the author of the book "Brave, Not Perfect: Fear Less, Fail More, and Live Bolder."
