Book excerpt: With empowering insights to help women navigate the narrowest corridors of sexism, tech-industry pioneer Magdalena Yesil shares on-the-ground career advice that is as powerful as any MBA Pioneering Silicon Valley entrepreneur and investor Magdalena Yesil came to the United States in 1976 with two suitcases and $43, blind to the challenges she would face as a woman and immigrant in Silicon Valley. Today, she is best known as the first investor and a founding board member of Salesforce, the now-multibillion dollar company that ushered in the era of cloud-based computing. In Power Up: How Smart Women Win in the New Economy, Yesil urges women to look beyond the alarming gender statistics of the workplace and feel confident entering tech or any field-but also to be prepared to deal with the challenges. She shares what she experienced as a woman in Silicon Valley with surprising candor and heart, relying not just on her insight but that of more than a dozen top women entrepreneurs to offer pragmatic takeaways on topics such as: · Owning career choices while managing risk · Getting credit for your work · Managing sexual dynamics · Recruiting allies in the movement toward a supportive workplace for everyone Pragmatic, incisive, and full of highly actionable advice, Yesil prepares ambitious women to break glass ceilings and rise to the top in the New Silicon Valley -- and beyond.
