With three interviews to her credit, Sally Helgesen is not only one of our favorite Cool Friends, she's tied for first place in frequency of Cool Friends solo interviews (with the prolific Seth Godin!). She also has a section of Tom's Mother of All Presentations devoted to her work. Best known for her 1990 classic, The Female Advantage, Sally has a focus on women's work issues, but her insights are universal—perhaps essential for all who would succeed at work in the 21st Century.
Interview No.1, posted 2000. Book under discussion: The Web of Inclusion: A New Architecture for Building Great Organizations.
Interview No.2, posted 2002, and the book: Thriving in 24/7: Six Strategies for Taming the New World of Work.
We'd suggest you read all three interviews and maybe pick up a couple of Sally's books, too!
