Picture the archetypal CEO. If you’re typical, you imagine a man or a woman in his or her 50s. Firm handshake. No nonsense. Good teeth. Majored in finance in college and went on to get an MBA from an Ivy League business school. Left-brain thinkers, he or she knows his or her way around a spreadsheet and a boardroom. It is time to update the picture in your head, because the future belongs to the storydoers.
