The good news is that you don’t need to be a marketing or technical genius or a charismatic visionary to be a highly effective CEO. You do, however, need to understand capital allocation and to think carefully about how to best deploy your company’s resources to create value for shareholders. You have to be willing to always ask what the return is and to go forward only with projects that offer attractive returns using conservative assumptions. And you have to have the confidence to occasionally do things differently from your peers.
